Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a protection device for a reciprocating compressor. Background Technology

[0002] A compressor is a mechanical device used to increase the pressure of a gas and reduce its volume. It typically uses external force to compress the gas within a closed space and is widely used in air conditioning, refrigerators, refrigeration, pneumatic tools, and many industrial processes. A reciprocating compressor is a mechanical device that compresses gas through the reciprocating motion of a piston. Its working principle is similar to the piston system in an internal combustion engine and a car engine. The core components of a reciprocating compressor are the piston, cylinder, crankshaft, and connecting rod. A compressor protection device is a safety device used to protect the compressor from malfunctions and damage. By monitoring the compressor's operating status in real time, it detects abnormalities and automatically takes measures when malfunctions and risks occur, such as stopping the compressor's operation and issuing alarms. This prevents serious damage to the compressor due to overload, overheating, low oil pressure, etc., extends its service life, and ensures safe operation.

[0003] Existing technology patent document CN218293796U discloses a compressor protection device, including a body, an outer cover, an air vent on the outer cover, a connecting mechanism on the outer end face of the air vent, a plug-in mechanism connected within the connecting mechanism, a ventilation mechanism on the plug-in mechanism, and a fixing mechanism between the ventilation mechanisms. This utility model uses a fan that blows air into the inner part of the outer cover through a conical nozzle, thereby achieving heat dissipation inside the outer cover, reducing the internal temperature of the outer cover, and thus cooling the compressor body, providing protection for the compressor and enabling it to operate efficiently.

[0004] In the existing technology, some devices protect the compressor by simply dissipating heat, which means that the compressor cannot be protected from external damage, thus affecting the compressor's service life. Utility Model Content

[0006] To achieve the above objectives, this utility model provides a reciprocating compressor protection device, including a protective shell, a protective mechanism fixedly connected inside the protective shell, and a maintenance mechanism detachably connected to the rear outer side of the protective shell.

[0007] The protective mechanism includes a large vent plate, which is fixedly connected to the outside of the protective shell. A heat dissipation pipe is fixedly connected to the inside of the large vent plate. Two fans a are fixedly connected to the upper inside of the protective shell. A connecting assembly is fixedly connected to the bottom of the protective shell. Rotating balls are rotatably connected to the four corners of the bottom of the connecting assembly. A buffer assembly is fixedly connected to the bottom of the rotating balls. A limit shell is fixedly connected to the outside of the buffer assembly.

[0008] The maintenance mechanism includes a rear cover shell, which is detachably connected to the rear side of the protective shell. Multiple bolts are threaded internally onto the rear cover shell, and the bolts are threaded externally onto the rear side of the protective shell. Multiple protruding pieces are fixedly connected externally to the rear cover shell, and multiple recessed pieces are fixedly connected externally to the protective shell.

[0010] The buffer assembly includes a telescopic column, one end of which is fixedly connected to the bottom of the rotating ball, and a spring is sleeved on the outside of the telescopic column.

[0011] The installation component includes a limiting strip, which is fixedly connected to the outside of the small leak plate, and a collection box is fixedly connected to the bottom of the small leak plate.

[0012] One end of the spring is fixedly connected to the bottom of the rotating ball, and the other end of the spring is fixedly connected to the inside of the limiting shell.

[0013] The four corners of the cuboid cavity are rotatably connected to the outside of the rotating ball, and the other ends of the multiple telescopic columns are fixedly connected to the four corners of the limiting shell.

[0014] The limiting strip is externally slidably connected to the inner groove of the rotating door, and the outer side of the rotating door is slidably connected to the outside of the collection box.

[0015] 1. This utility model provides a reciprocating compressor protection device. By installing fans a at both the upper and lower ends of the compressor, air convection is achieved, thereby dissipating heat. A rotating ball is provided at the bottom of the compressor. When subjected to external impact, the rotating ball will rotate in the opposite direction of the force inside the compressor. With the cooperation of the telescopic column and the spring, the external impact force is reduced, thus achieving multi-directional protection for the compressor and extending the service life of the compressor.

The present invention provides a reciprocating compressor protection device, which uses a convex plate and a groove plate to connect, and then uses bolts to connect the rear cover to the feed port, so that the rear cover can be installed accurately and quickly. At the hole of the rotating door, a limiting strip drives the small slug to slide out, and the bottom of the small slug is provided with a collection box, so that the dust accumulated on the outside of the small slug will not fall into the inside, thus ensuring the cleanliness of the inside.

[0024] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0025] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a reciprocating compressor protection device, including a protective shell, which is generally rectangular in structure, has good protective performance and corrosion resistance, and can provide reliable protection for the internal compressor components, preventing damage from the external environment. A protective mechanism 2 is fixedly connected inside the protective shell 1. The protective mechanism 2 includes a large perforated plate 21, which is rectangular in structure and has multiple regularly arranged perforations on its surface. This effectively filters dust and impurities from the air, preventing them from entering the protective shell 1, while allowing airflow for heat dissipation. The large perforated plate 21 is fixedly connected to the outside of the protective shell 1. A heat dissipation pipe 22 is fixedly connected inside the large perforated plate 21. The heat dissipation pipe 22 is cylindrical in structure, and the internal coolant circulation effectively reduces the temperature inside the protective shell 1. Temperature is ensured to keep the compressor operating within the normal temperature range. Two fans a23 are fixedly connected to the upper part of the inner side of the protective shell 1. The fans a23 can generate a strong airflow when working, which accelerates the discharge of heat inside the protective shell 1 and further improves the heat dissipation effect. A connecting component 24 is fixedly connected to the bottom of the protective shell 1. The connecting component 24 includes a cuboid cavity 241. The cuboid cavity 241 has a cuboid structure. The four corners inside the cuboid cavity 241 are rotatably connected to the outside of the rotating ball 25. The other ends of multiple telescopic columns 261 are fixedly connected to the four corners inside the limiting shell 27. The top of the cuboid cavity 241 is fixedly connected to the top of the protective shell 1. Two fans b242 are fixedly connected inside the cuboid cavity 241. They work with the fans a23 to realize air convection inside the protective shell 1 and further enhance the heat dissipation effect inside the protective shell 1.

[0026] Rotating balls 25 are rotatably connected to the four bottom corners of the connecting assembly 24. A buffer assembly 26 is fixedly connected to the bottom of the rotating balls 25. The buffer assembly 26 includes a telescopic column 261. The telescopic column 261 has a cylindrical structure, good elasticity and wear resistance, and can extend and retract within a certain range to play a buffering role. One end of the telescopic column 261 is fixedly connected to the bottom of the rotating balls 25. A spring 262 is sleeved on the outside of the telescopic column 261. When the telescopic column 261 extends and retracts, the spring 262 can provide a certain elastic force to play a buffering and shock-absorbing role, effectively protecting the compressor from external impacts. One end of the spring 262 is fixedly connected to the bottom of the rotating balls 25, and the other end of the spring 262 is fixedly connected to the inside of the limiting shell 27. The limiting shell 27 is fixedly connected to the outside of the buffer assembly 26 to play a limiting and protective role, preventing the telescopic column 261 and the spring 262 from shifting or being damaged during movement.

[0027] like Figures 3-5 As shown, a maintenance mechanism 3 is detachably connected to the rear side of the protective shell 1. The maintenance mechanism 3 includes a rear cover 31, which has a rectangular structure. The rear cover 31 is detachably connected to the rear side of the protective shell 1. Multiple bolts 32 are threaded inside the rear cover 31, which allows the rear cover 31 to be easily installed and removed, facilitating the maintenance and repair of the internal components of the protective shell 1. The bolts 32 are threaded inside the rear side of the protective shell 1. Multiple protrusions 33 are fixedly connected to the outside of the rear cover 31. The grooves 34 have a rectangular groove structure. The cooperation between the protrusions 33 and the grooves 34 can effectively prevent the rear cover 31 from pre-aligning and shifting during installation, ensuring a tight connection with the protective shell 1. Multiple grooves 34 are fixedly connected to the outside of the protective shell 1. The protrusions 33 are slidably connected to the inside of the grooves 34.

[0028] The protective shell 1 is internally connected to a rotating door 35, which allows for easy opening and closing, facilitating operation inside the protective shell 1. Multiple small perforated plates 36 are slidably connected to the outer side of the rotating door 35. These plates 36 have a rectangular structure and multiple small perforations on their surface, filtering dust and impurities entering through the rotating door 35 while allowing airflow for auxiliary heat dissipation. Mounting components 37 are fixedly connected to the upper and lower ends of the buffer assembly 26. The mounting components 37 include limiting strips 371, which limit… The positioning strip 371 has a long strip structure and serves as a limit and guide to ensure the stable installation and sliding of the small drain plate 36 inside the rotating door 35. The outer side of the positioning strip 371 is slidably connected to the inner groove of the rotating door 35, and the outer side of the rotating door 35 is slidably connected to the outer side of the collection box 372. The outer side of the positioning strip 371 is fixedly connected to the outer side of the small drain plate 36. The outer bottom of the small drain plate 36 is fixedly connected to the collection box 372 for collecting dust and impurities that leak from the small drain plate 36, which facilitates regular cleaning and keeps the inside of the protective shell 1 clean.

[0029] Working principle: First, when the compressor is running, the two fans a23 at the upper end of the protective shell 1 and the two fans b242 in the cuboid cavity 241 start synchronously, forming a bidirectional airflow. The air enters the heat dissipation pipe 22 through the holes of the large perforated plate 21 for convection heat dissipation. When the device is subjected to external impact, the rotating ball 25 rotates in the cuboid cavity 241 in the direction of impact, causing the telescopic column 261 of the buffer assembly 26 to contract axially. At the same time, the spring 262 absorbs kinetic energy through deformation, and the limiting shell 27 restricts the displacement range of the buffer assembly 26, thereby achieving multi-directional shock absorption.

[0030] When performing maintenance, the operator first aligns the protrusion 33 of the rear cover 31 with the groove 34 of the protective shell 1 to complete the pre-positioning, and then tightens the rear cover 31 with bolts 32. When the rotating door 35 is opened, the limiting strip 371 at its hole is linked with the small leak plate 36 to slide out along the groove inside the rotating door 35, and slide out the fully loaded collection box 372 for cleaning.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art will understand that all or part of the processes for implementing the above embodiments and equivalent variations made in accordance with the claims of this application are still within the scope of this application.
