An improved screw chiller unit with vibration damping function

Abstract

This invention discloses an improved screw chiller unit with vibration damping function, belonging to the technical field of screw chiller units. It includes two side plates, an expansion valve, and a control cabinet. An evaporator and a condenser are arranged on opposite sides of the outer surfaces of the two side plates. A screw compressor assembly is mounted on the top of the outer surface of the evaporator. The expansion valve is located on one side of the outer surface of the condenser. The control cabinet is located on the top of the outer surface of the condenser. A connection port for connecting to a water tower is provided on one side of the evaporator. This improved screw chiller unit with vibration damping function, through the installation of a vibration damping protection device, ensures that the entire side plate does not move upwards when the side plate moves upwards, causing the first grounding nail to move.

Description

Technical Field

[0001] This invention belongs to the technical field of screw chiller units, specifically an improved screw chiller unit with vibration damping function. Background Technology

[0002] A screw chiller is a chiller unit with various types of screw compressors as the main unit. It is an assembled refrigeration device composed of a screw refrigeration compressor, condenser, evaporator, thermostatic expansion valve, oil separator, as well as automatic control components and instruments.

[0003] Existing screw chiller units mainly consist of a screw compressor assembly, side plates, evaporator, condenser, expansion valve, control cabinet, and connection ports. During use, the screw compressor assembly exchanges the coolant in the condenser with the coolant in the condenser, and then, under the action of the expansion valve, the coolant flows to the water tower connected to the connection port, thereby achieving the cooling effect.

[0004] However, in actual use, since the entire device is generally installed outdoors, it is very susceptible to severe weather conditions, such as strong winds, which can cause the device to shake and vibrate. The components of the device itself will also vibrate significantly. The side plates that are fixed to the ground with nails or screws are very easy to loosen, causing the nails or screws to separate from the ground, which intensifies the overall vibration and is very inconvenient. Summary of the Invention

[0005] (a) Technical problems to be solved

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This improved screw chiller unit with shock absorption function, through the installation of a shock absorption protection device, under the action of the V-shaped plate, when the side plate moves upward and drives the first ground nail to move, the movement of the first ground nail will cause the V-shaped plate to rotate on the outer surface of the first fixed rod, thereby sliding the arc plate into the arc groove. At this time, it can ensure that the entire side plate will not move upward, but will be unloaded by the V-shaped plate, thus playing a shock absorption role. Under the action of the first threaded rod, the first screw hole block will move, which will in turn drive the rectangular rod to move, so that the rectangular rod can drive the second ground nail to move, allowing the second ground nail to drill into the ground and be fixed. Furthermore, with the cooperation of the fourth rectangular plate and the first operating block, the first ground nail can be reinforced, thus playing a seismic resistance role.

[0022] 2. This improved screw chiller unit with shock absorption function is equipped with an accidental support device. When encountering large vibrations, causing excessive shaking of the entire unit, the evaporator and condenser located between the side plates are prone to separation from the side plates due to the control cabinet and screw compressor assembly installed on top, and may fall directly to the ground and cause damage. At this time, under the action of the second threaded rod and the first threaded cylinder, the arc-shaped support plate can fit against the evaporator and condenser. When the evaporator and condenser separate, they can be supported by the arc-shaped support plate, and then buffered by the action of the second and third springs to avoid direct fall damage.

[0023] 3. This improved screw chiller unit with shock absorption function, by setting up a shielding and protective device, can drive the shielding plate to move upward under the action of the third threaded rod and the second threaded cylinder, thereby causing the circular block to rotate on the second fixed rod and the roller to slide in the second rectangular groove. At this time, the shielding plate will change from a horizontal state to an inclined state, thereby guiding rainwater on rainy days and preventing it from accumulating at the top.

A V-shaped plate 74 is inverted on the outer surface of the first fixing rod 73. The V-shaped plate 74 is located on the inner wall of the first rectangular through groove 71. A first rectangular plate 75 and a second rectangular plate 76 are fixedly connected to both sides of the outer surface of the V-shaped plate 74, respectively. By setting the V-shaped plate 74, it can cooperate with the first fixing rod 73 and the arc-shaped plate 710 to firmly fix the side plate 1.

A first operating block 78 is fixedly connected to one side of the outer surface of the first rectangular plate 75. The curved plate 710 can cooperate with the curved groove 713, so that when the first ground nail 77 moves upward, it moves to the lower left, thus preventing the side plate 1 from separating from the ground.

[0037] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the auxiliary stabilizing structure 79 includes a first rectangular frame 791.

A first threaded hole block 794 is threadedly connected to the outer surface of the first threaded rod 793. By setting the first threaded rod 793 and the first threaded hole block 794, the first threaded rod 793... This mechanism can drive the first screw hole block 794 to move, thereby cooperating with other components to perform their functions. The outer surface of the first screw hole block 794 is slidably connected to the inner wall of the first rectangular frame 791. Third rectangular through slots 795 are provided on both sides of the outer surface of the first rectangular frame 791. A rectangular rod 796 is fixedly connected to one side of the outer surface of the first screw hole block 794. By setting the rectangular rod 796, it can cooperate with the first screw hole block 794 to move. The rectangular rod 796 is L-shaped, and the outer surface of one of the angled edges of the rectangular rod 796 is slidably connected to the inner wall of the third rectangular through slot 795. The rectangular rod 796 is away from the first screw hole block 794. One end of the first rectangular rod 796 is fixedly connected to a third rectangular plate 797. A first dovetail slide rod 799 is fixedly connected to the bottom of the outer surface of the third rectangular plate 797. One end of the first dovetail slide rod 799 is slidably connected to a first cylindrical body 7910. By setting the first dovetail slide rod 799 and the first cylindrical body 7910, the upward force of the first ground nail 77 can be buffered. A fourth rectangular plate 7911 is fixedly connected to the bottom of the outer surface of the first cylindrical body 7910. A second ground nail 7913 is slidably inserted into the inner wall of the fourth rectangular plate 7911. A rectangular thin rod 798 is provided on the other side of the rectangular rod 796 at the bend. The thin rod 798 is designed to break first and protect other components when subjected to a large impact. The outer surface of the first dovetail slide rod 799 is fitted with a first spring 7912. The two ends of the first spring 7912 are fixedly connected to the top of the outer surface of the first cylindrical body 7910 and the bottom of the outer surface of the third rectangular plate 797, respectively. The top of the outer surface of the second ground nail 7913 is fixedly connected with a second operating block 7914. The bottom of the outer surface of the fourth rectangular plate 7911 is provided with a circular groove. The outer surface of the first operating block 78 is engaged with the inner wall of the circular groove. By providing the circular groove, it can cooperate with the first operating block 78 to perform its function.

[0038] Specifically, such as Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the accidental support device 8 includes two connecting plates 81. One side of the outer surface of each connecting plate 81 is fixedly connected to one side of the outer surface of each of the two side plates 1. A U-shaped frame 82 is fixedly connected to the top of the outer surface of the connecting plate 81. A second motor 84 is fixedly installed on the top of the inner wall of the U-shaped frame 82. A second threaded rod 85 is fixedly connected to the output end of the second motor 84. A first threaded cylinder 86 is threadedly connected to the outer surface of the second threaded rod 85. By setting the second threaded rod 85 and the first threaded cylinder 86, the second threaded rod 85 can drive the first threaded cylinder 86 to move, thereby cooperating with other parts. The components function as follows: a second cylindrical body 87 is fixedly connected to the top of the outer surface of the first threaded cylinder 86; a second dovetail slide rod 88 is slidably connected to the inner wall of the top of the second cylindrical body 87; and a fifth rectangular plate 89 is fixedly connected to the top of the second dovetail slide rod 88. By setting the second cylindrical body 87 and the second dovetail slide rod 88, the second dovetail slide rod 88 can slide on the inner wall of the second cylindrical body 87, thereby cooperating with the second spring 810 for buffering. The second spring 810 is sleeved on the outer surface of the second dovetail slide rod 88, and the two ends of the second spring 810 are respectively connected to the top of the outer surface of the second cylindrical body 87.

By setting the third dovetail slide rod 812 and the third cylindrical body 811, the third dovetail slide rod 812 can slide on the inner wall of the third cylindrical body 811, thereby cooperating with the third spring 813 to achieve a buffering effect. The top of the outer surface of the third cylindrical body 811 is flush with the outer surface of the fifth rectangular plate 89. The bottom of the surface is fixedly connected. The outer surface of the third dovetail slide rod 812 is fitted with a third spring 813.

The top of the outer surface of the connecting block 814 is fixedly connected with an arc-shaped support plate 815. The inner wall of the arc-shaped support plate 815 is provided with a rectangular through hole 816. By setting the rectangular through hole 816, the heat dissipation effect between the arc-shaped support plate 815 and the contact surface of the evaporator 2 and the condenser is avoided.

[0039] Specifically, such as Figure 1 , Figure 8 and Figure 9As shown, the shielding and protective device 9 includes an L-shaped plate 91 and a support rod 915. One side of the outer surface of the L-shaped plate 91 is fixedly connected to one side of the outer surface of the control cabinet 4. The bottom end of the support rod 915 is fixedly connected to the top of the outer surface of the control cabinet 4. A third motor 92 is fixedly installed on the bottom of the outer surface of the L-shaped plate 91. A third threaded rod 93 is fixedly connected to the output end of the third motor 92. A second threaded cylinder 94 is threadedly connected to the outer surface of the third threaded rod 93. By setting the third threaded rod 93 and the second threaded cylinder 94, the third threaded rod 93 can drive the second threaded cylinder 94 to move, thereby cooperating with other components to play a role. An auxiliary block 95 is fixedly connected to the outer surface of the second threaded cylinder 94. A first rectangular groove 97 is opened on one side of the inner surface of the L-shaped plate 91. A dovetail slider 96 is slidably connected to the inner wall of the first rectangular groove 97. The outer surface of the dovetail slider 96 is fixedly connected to the outer surface of the auxiliary block 95. By setting the dovetail slider 96, the second threaded cylinder 94 can be fixedly connected to the auxiliary block 95. The threaded cylinder 94 is limited. A U-shaped plate 98 is fixedly connected to the top of the outer surface of the second threaded cylinder 94. A second fixing rod 99 is fixedly connected between the two sides of the inner wall of the U-shaped plate 98. A circular block 910 is fixedly connected to the outer surface of the second fixing rod 99. A connecting circular block 911 is fixedly connected to the outer surface of the circular block 910. A shielding plate 912 is fixedly connected to the outer surface of the connecting circular block 911. By setting the shielding plate 912, the control cabinet 4 can be protected from rain and sun. A second rectangular groove 913 is opened at the bottom of the outer surface of the shielding plate 912. A third rectangular groove 914 is opened on both sides of the inner wall of the second rectangular groove 913. A U-shaped frame 916 is fixedly connected to the top of the support rod 915. A rotating rod 917 is rotatably arranged between the two sides of the inner wall of the U-shaped frame 916. A roller 918 is fixedly connected to the outer surface of the rotating rod 917. The rotating rod 917 is set on the inner wall of the third rectangular groove 914. The roller 918 is set on the inner wall of the second rectangular groove 913.

[0040] The working principle of this invention is as follows:

[0041] S1. When the side plate 1 encounters an upward force, it will cause the first ground nail 77 to move upward, which will in turn cause the V-shaped plate 74 to rotate on the outer surface of the first fixed rod 73, and then cause the arc plate 710 to slide into the arc groove 713. At this time, even if the first ground nail 77 is separated from the ground, the side plate 1 will not be separated from the ground. The upward movement of the first ground nail 77 will cause the first dovetail slide rod 799 to slide on the inner wall of the first cylindrical body 7910, which will cause the first spring 7912 to deform, thus playing a buffering role. The second ground nail 7913 will also play an auxiliary fixing effect.

[0042] S2. When it is necessary to prevent the evaporator 2 and the condenser from separating, the second motor 84 is started, which drives the second threaded rod 85 to rotate. The second threaded rod 85 drives the first threaded cylinder 86 to move, which in turn drives the second cylindrical body 87, the second dovetail slide rod 88 and the fifth rectangular plate 89 to move, which in turn drives the arc-shaped support plate 815 to move and fit with the evaporator 2 and the condenser. When separation occurs, the second dovetail slide rod 88 can slide on the inner wall of the second cylindrical body 87, and the third dovetail slide rod 812 can slide on the inner wall of the third cylindrical body 811, which in turn causes the second spring 810 and the third spring 813 to deform, thus achieving a buffering effect.

[0043] S3. When it is necessary to store rainwater in the control cabinet 4, the third motor 92 is started, which drives the third threaded rod 93 to rotate, which in turn drives the second threaded cylinder 94 to move. The second threaded cylinder 94 drives the auxiliary block 95 to move, which in turn drives the dovetail slider 96 to slide in the first rectangular groove 97. At this time, the baffle plate 912 is driven to move, which in turn drives the circular block 910 to rotate on the outer surface of the second fixed rod 99. At the same time, the roller 918 slides in the second rectangular groove 913, which makes the baffle plate 912 tilt, thereby guiding the rainwater.
