Description

Technical Field

[0001] This utility model belongs to the field of heat pump installation technology, and in particular relates to a fixing device for heat pump units. Background Technology

[0002] Heat pumps, as highly efficient energy utilization devices, are widely used in heating, cooling, and hot water supply applications. Heat pump units generate some vibration during operation, and due to their large size and weight, they require reliable mounting hardware to connect to the ground to ensure operational stability and safety.

[0003] The existing method of fixing heat pump units is to directly fix the channel steel of the supporting structure to the ground with simple bolts. This lacks precise positioning and force distribution components. The vibration generated by the unit operation can easily cause the bolts to loosen over time, and displacement may occur after long-term use, affecting the reliability of the fixation. At the same time, the bolts directly penetrating the channel steel may also reduce its structural strength.

[0004] To address the problems of insufficient stability and easy damage to the support structure in existing fixing methods, this utility model proposes a heat pump unit fixing device with reasonable structure, reliable fixing and convenient assembly and disassembly. Utility Model Content

[0005] This utility model aims to solve the technical problems of insufficient fixation stability and easy damage to the support structure of existing heat pump units, and provides a fixing device for heat pump units.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: it includes a heat pump unit, which includes a support structure, a heat dissipation component, and an internal heat conversion module. The support structure is composed of several transverse channel steels connected to longitudinal channel steels. The bottommost transverse channel steel of the heat pump unit is connected to the ground. Several connecting and fixing components are distributed on the bottommost transverse channel steel of the heat pump unit. The connecting and fixing components include a supporting connector disposed at the bottom of the transverse channel steel, and a limiting connector that passes through the transverse channel steel from the side and connects to the supporting connector.

[0007] Furthermore, the supporting connector includes a T-shaped metal plate, with a slot at the short vertical end of the T-shaped metal plate and connecting holes at both ends of the long end of the T-shaped metal plate.

[0008] Furthermore, a nut sleeve with internal threads is fixedly provided on the upper surface of the T-shaped metal plate, and semi-cylindrical positioning protrusions are also fixedly provided on the T-shaped metal plate surfaces on both sides of the nut sleeve.

[0009] Furthermore, the limiting connector includes a base body, and a sleeve block and a plug block fixedly provided at both ends of the bottom of the base body. The base body passes through the hole opened on the transverse channel steel, so that the sleeve block is located on the outside of the transverse channel steel and the plug block is located on the inside of the transverse channel steel.

[0010] Furthermore, the bottom of the sleeve block has a hole or groove for the nut sleeve to be inserted therein. A connecting screw passes through the top of the sleeve block and is screwed into the inside of the nut sleeve for connection. The bottom of the sleeve block also has a positioning groove that engages with the positioning protrusion.

[0011] Furthermore, the plug block is inserted into the inside of the slot, and after passing through the base, the transverse channel steel, and the T-shaped metal plate with connecting screws, it is fastened with nuts.

[0012] Furthermore, the connection hole is connected to the ground via screws and nuts.

[0013] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: 1. In this utility model, precise positioning is achieved by the engagement of the positioning protrusion and the positioning groove, avoiding horizontal displacement; the double connection between the sleeve block and the nut sleeve, and the plug block and the slot, combined with the screw fastening, forms a three-dimensional fixed structure, effectively resisting the risk of loosening caused by unit vibration; 2. In this utility model solution, no welding is required, and all connections are achieved by screws and nuts. When disassembling, only the corresponding screws need to be unscrewed to separate the parts, without damaging the support structure and the ground, which facilitates the maintenance and relocation of the unit; 3. In this utility model, the supporting connector and the limiting connector form a wrapping fixation, which avoids structural damage caused by the screws directly penetrating the channel steel. At the same time, the T-shaped metal plate increases the stress area and disperses the pressure of the unit weight on the ground. 4. In this utility model, the connecting and fixing components can be flexibly distributed according to the length of the longitudinal channel steel, which is suitable for the support structure of heat pump units of different specifications and has strong versatility.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Example 1 Combination Figures 1 to 7 The illustrated mounting device for a heat pump unit includes a heat pump unit, which includes a support structure 1, a heat dissipation component, and an internal heat conversion module. The support structure 1 is composed of several transverse channel steels 11 connected to longitudinal channel steels 12. The bottommost transverse channel steel 11 of the heat pump unit is connected to the ground. Several connecting and fixing components 2 are distributed on the bottommost transverse channel steel 11 of the heat pump unit. The connecting and fixing components 2 include a supporting connector 21 disposed at the bottom of the transverse channel steel 11, and a limiting connector 22 that passes through the transverse channel steel 11 from the side and connects to the supporting connector 21.

[0018] The supporting connector 21 includes a T-shaped metal plate 211, with a slot 212 at the short vertical end of the T-shaped metal plate 211 and connection holes 213 at both ends of the long plate end of the T-shaped metal plate 211.

[0019] The upper surface of the T-shaped metal plate 211 is fixed with a nut sleeve 214 with internal threads, and semi-cylindrical positioning protrusions 215 are also fixed on the surface of the T-shaped metal plate 211 on both sides of the nut sleeve 214.

[0020] The limiting connector 22 includes a base 221, and a sleeve block 222 and a plug block 223 fixedly provided at both ends of the bottom of the base 221. The base 221 passes through the hole opened on the transverse channel steel 11, so that the sleeve block 222 is located outside the transverse channel steel 11 and the plug block 223 is located inside the transverse channel steel 11.

[0021] The bottom of the sleeve block 222 has a hole and groove 224 for the nut sleeve 214 to be inserted into. The connecting screw passes through the top of the sleeve block 222 and is screwed into the inside of the nut sleeve 214 for connection. The bottom of the sleeve block 222 also has a positioning groove 225 that engages with the positioning protrusion 215.

[0022] The plug block 223 is inserted into the inside of the slot 212, and is then connected and tightened by connecting screws through the base 221, the transverse channel steel 11, and the T-shaped metal plate 211, and finally by nuts.

[0023] The connecting hole 213 is connected to the ground by screws and nuts, increasing the number of connection points and improving the fixing effect and stability.

[0024] Example 2 1.1 Component Preparation Support structure 1: Standard channel steel is used for processing. The transverse channel steel 11 and the longitudinal channel steel 12 are connected by bolts to form a frame structure. Holes that are compatible with the base 221 are opened on the transverse channel steel 11 at the position of the limiting connector 22. Support connector 21: T-shaped metal plate 211 is made of stainless steel to ensure strength and corrosion resistance; slot 212 is opened in the middle of the short vertical end, and the connecting hole 213 is a through hole with a smooth inner wall; nut sleeve 214 is fixed to the middle of the upper surface of T-shaped metal plate 211 by welding, and its inner diameter matches the specifications of the connecting screw; positioning protrusion 215 is a semi-cylindrical structure and is symmetrically welded to both sides of nut sleeve 214; Limiting connector 22: The base 221, sleeve block 222 and plug block 223 are integrally formed and made of high-strength carbon steel; the size of the hole groove 224 is adapted to the outer diameter of the nut sleeve 214, and the curvature of the positioning groove 225 is consistent with the positioning protrusion 215 to ensure tight engagement; through holes are opened at corresponding positions of the base 221, the transverse channel steel 11 and the T-shaped metal plate 211 for inserting connecting screws.

[0025] 1.2 Assembly Steps Place the supporting connector 21: Place the long end of the T-shaped metal plate 211 horizontally at the preset position on the ground, ensuring that the connecting hole 213 is aligned with the fixing hole reserved on the ground; Positioning support structure: Place the horizontal channel steel 11 at the bottom of the heat pump unit above the short vertical end of the T-shaped metal plate 211, and adjust the position so that the holes on the horizontal channel steel 11 correspond to the positions of the supporting connectors 21. Install the limiting connector 22: Pass the base 221 through the hole of the transverse channel steel 11, so that the sleeve block 222 fits against the outside of the transverse channel steel 11 and the plug block 223 is inserted into the slot 212; at this time, the nut sleeve 214 is inserted into the hole slot 224, and the positioning protrusion 215 and the positioning groove 225 are precisely engaged. Fastening connection: First, use connecting screws to pass through the sleeve block 222 and screw them into the nut sleeve 214 to tighten and fix it; then use connecting screws to pass through the base 221, the transverse channel steel 11 and the T-shaped metal plate 211 in sequence, and tighten them with nuts; finally, use screws and nuts to fix the T-shaped metal plate 211 to the ground through the connecting hole 213 to complete the assembly of the entire device.

[0026] 1.3 Working Principle Positioning mechanism: The meshing structure of the positioning protrusion 215 and the positioning groove 225 restricts the horizontal displacement between the limiting connector 22 and the supporting connector 21, thereby fixing the horizontal position of the transverse channel steel 11 and avoiding the displacement caused by the vibration of the unit operation. Fixing mechanism: The sleeve block 222 and the nut sleeve 214 are fitted together and the top screw is tightened to form the first layer of fixation in the longitudinal direction; the plug block 223 and the slot 212 are fitted together and the through screw is tightened to form the second layer of fixation in the longitudinal direction. The double fixing structure effectively resists the risk of loosening caused by vibration. Stress Dispersion: The long end of the T-shaped metal plate 211 increases the contact area with the ground, distributing the weight of the unit evenly to the ground and reducing local pressure; at the same time, the supporting connector 21 and the limiting connector 22 form a wrapping support for the transverse channel steel 11 from the top, bottom and sides, avoiding structural deformation caused by excessive local stress.

[0027] 1.4 Disassembly Process When it is necessary to disassemble the unit, first unscrew the screws that are fixed to the ground at the connection hole 213, then unscrew the connecting screws that penetrate the base 221 and the connecting screws on the top of the sleeve block 222 in sequence, and finally pull the limiting connector 22 out of the hole in the transverse channel steel 11 to separate the support structure and the supporting connector, thus completing the disassembly.
