[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1

[0043] See also Figure 1-Figure 16 The present invention provides a water-cooled screw unit that is easy to install and disassemble, and the water-cooled screw unit that is easy to install and disassemble comprises: a base plate 1 and a machine component 2 located on the base plate 1;

[0044] The machine assembly 2 includes a screw compressor, an evaporator, a condenser, an oil-liquid separator, a filter and a cooling box;

[0045] Four connecting members are movably arranged on the base plate 1, and a movable plate 4 is rotatably connected between two adjacent connecting members, and a stretchable quadrilateral is formed between the connecting members and the movable plates 4, wherein the sides of the two movable plates 4 are respectively provided with fixed plates 5, and the fixed plates 5 are provided with adjusting members that slide with the base plate 1, and the connecting members and the adjusting members are connected by a belt 3, and the connecting members and the adjusting members are respectively connected to the components of the machine assembly 2 in a one-to-one correspondence;

[0046] The fixed plate 5 is provided with a matching component for adjusting the position of the adjusting member, and an adjusting component for driving the adjusting member to rotate is provided between the fixed plate 5 and the movable plate 4;

[0047] A control panel 6 is rotatably connected to one of the connecting members, and a lifting component is provided at the end of the control panel 6. The base plate 1 is also provided with a stabilizing component for inserting and fixing one of the connecting members and pressing and fixing the belt 3.

[0048] Through the movable control plate 6, the plurality of movable plates 4 are moved, and the matching components are adaptively adjusted to ensure that the belt 3 is always in a stretched state, so that the machine components 2 located on the connecting parts are separated from each other.

[0049] First, remove the connecting pipes between the screw compressor, evaporator, condenser, oil separator, filter and cooling box (not shown in the figure). The connecting pipes can also be adaptively increased to ensure that the separation process will not pull the connecting pipes.

[0050] Then, the multiple movable panels 4 are unfolded through the movable control panel 6, so that the connecting parts are moved away from each other, and the screw compressor, evaporator, condenser, oil-liquid separator, filter and cooling box located on the connecting parts and the adjusting parts are moved away from each other, and the state of close contact is switched to a state of being away from each other, so as to avoid space and facilitate the operator to inspect and replace the machine component 2;

[0051] In the close contact state, the screw compressor, the evaporator, the condenser, the oil-liquid separator, the filter and the cooling box are close to each other, and the pressing member 23 is stuck in the groove 24;

[0052] By pulling out the control panel 6, the screw compressor, evaporator, condenser, oil-liquid separator, filter and cooling box are moved away from each other, thus switching to the unfolded state, and the pressing member 23 is disengaged from the groove 24, so that the screw compressor, evaporator, condenser, oil-liquid separator, filter and cooling box are lifted up;

[0053] While the movable control panel 6 is being moved, the movable panel 4, the fixed panel 5 and the machine assembly 2 are lifted upward by the lifting assembly, so as to facilitate the operation of the staff on the bottom of the machine assembly 2;

[0054] After the inspection and replacement work is completed, the machine component 2 is reset, and the machine components 2 are moved away from each other and then moved closer and stabilized again, the occupied space is reduced, the lifting component is reset, and finally the belt is fixed by the stabilizing component to facilitate the normal use of the water-cooled screw unit.

[0055] The connecting member includes a first pulley 7 that is slidably matched with the base plate 1, a rotating shaft 8 that is rotatably connected to the movable plate 4 is fixedly connected to the first pulley 7, the control plate 6 is rotatably connected to the rotating shaft 8, and a connecting wheel 9 for installing the machine component 2 is plugged on the top of the rotating shaft 8, wherein the first pulley 7 that is diagonally related to the control plate 6 is provided with a plug-in rod at the bottom, and the plug-in rod is plugged on the base plate 1;

[0056] The adjusting member comprises a second pulley 10 which is slidably matched with the base plate 1 , the second pulley 10 is connected with an adjusting wheel 11 through a matching component, the adjusting wheel 11 is mounted with an organic component 2 , and the belt 3 is wound between the connecting wheel 9 and the adjusting wheel 11 .

[0057] When the water-cooled screw unit is in a contracted fixed state, the first pulley 7 connected to the control board 6 remains stationary due to the limit of the pressing member 23 and the groove 24. The first pulley 7 in a diagonal relationship with the control board 6 also remains stationary due to the plug-in rod at the bottom being plugged into the base plate 1. After the two diagonal corners of the quadrilateral are fixed, the other two corners also remain stationary, thus forming a stable structure.

[0058] Furthermore, by fixing the belt through a stabilizing component, the connecting wheel 9 can be kept in a relatively stable state.

[0059] The wheel surface of the adjusting wheel 11 is a smooth surface that is in sliding tension with the belt 3, and the wheel surface of the connecting wheel 9 is a rough surface that is in friction transmission with the belt 3;

[0060] When one of the connecting wheels 9 rotates, the other three connecting wheels 9 will be driven to rotate synchronously through the belt 3;

[0061] The adjusting wheel 11 mainly serves to tension the belt 3 and does not rotate synchronously with the rotation of the connecting wheel 9. Because the adjusting wheel 11 is located between the two connecting wheels 9, the spacing is relatively close, and synchronous rotation is prone to interference. Therefore, the adjusting wheel 11 is independently rotated and adjusted through the adjusting component.

[0062] When the movable plate 4 moves, the first pulley 7 and the second pulley 10 slide on the base plate 1, and under the action of the matching components, the belt 3 always remains in a straight state, and the connecting wheel 9 and the adjusting wheel 11 move with the movable plate 4, thereby facilitating the separation of the machine components 2 from each other and facilitating the maintenance and replacement work of the staff.

[0063] The mating component includes a sliding plate 12 rotatably connected to the adjusting wheel 11, the bottom of the sliding plate 12 is plugged into the second pulley 10, and a sliding groove 13 slidably matched with the sliding plate 12 is opened on the fixed plate 5, a compression spring 14 is provided between one sliding plate 12 and the movable plate 4, and a control component is provided between the other sliding plate 12 and the movable plate 4.

[0064] When the control panel 6 moves, the movable panels 4 move with each other, thereby driving the motor components 2 to move and move away from each other, making it easier for the staff to carry out maintenance and replacement work. The movable panels 4 interact with each other, thereby making the belt 3 move. Through the cooperation of the compression spring 14, the sliding plate 12 slides in the sliding groove 13, so that the adjusting wheel 11 corresponding to the position of the compression spring 14 is adaptively adjusted along the fixed plate 5, thereby ensuring that the belt 3 is always in a straight state.

[0065] The control assembly includes a threaded rod 15 rotatably connected to the movable plate 4 . The threaded rod 15 penetrates into the sliding groove 13 and is threadedly connected to the sliding plate 12 .

[0066] By manually rotating the threaded rod 15, the corresponding sliding plate 12 is slidably matched, so as to properly adjust the straightness of the belt 3 to avoid excessive or insufficient straightness.

[0067] The adjusting assembly includes a sleeve 16 and a fixing assembly. Two limit plates 17 are fixedly connected to the adjusting wheel 11 . The two limit plates 17 are distributed with a gap. Both sides of the inner wall of the sleeve 16 are slidably connected to the two limit plates 17 .

[0068] When the machine components 2 have moved away from each other, some parts of the machine components 2 need to be rotated, such as a condenser is placed between the screw compressor and the evaporator. After the screw compressor, evaporator and condenser are unfolded, the condenser located in the middle needs to adjust the angle to avoid space, so as to facilitate the maintenance and replacement of the screw compressor, evaporator and condenser by the staff;

[0069] By rotating the sleeve 16 , the limiting plate 17 is driven to rotate, so that the adjusting wheel 11 is rotated by an angle, and the adjusting wheel 11 and the sliding plate 12 are self-rotatingly matched, and the rotation of the adjusting wheel 11 does not affect the sliding plate 12 .

[0070] The fixing assembly includes an insertion rod 18, a through hole 19 is provided in the middle of the sleeve 16, a plurality of insertion holes 20 arranged in a linear array are provided on the movable plate 4, the through hole 19 is located in the gap between the two limit plates 17, and the insertion rod 18 is plugged and matched with the through hole 19 and the insertion hole 20. After the motor assembly 2 is adjusted by the adjusting wheel 11, the insertion rod 18 is inserted into the through hole 19 and the insertion hole 20 to fix the adjusted angle.

[0071] It is worth noting that compared with the traditional telescopic device, the two limit plates 17 in the present application are distributed with a gap, such a limit plate 17 will not affect the plug-in position of the plug-in rod 18, making the plug-in adaptable and convenient, while the traditional telescopic device is generally divided into a telescopic sleeve tube and a telescopic sleeve plate, and holes are opened on the telescopic sleeve plate and the telescopic sleeve tube. When the telescopic sleeve plate and the telescopic sleeve tube are contracted to a certain extent, the holes on the telescopic sleeve plate and the telescopic sleeve tube need to be aligned to be plugged in, which is inconvenient to operate.

[0072] The lifting assembly includes a telescopic plate 21 and a telescopic sleeve 22 which are socketed with each other. The end of the telescopic plate 21 is connected and fixed to the end of the control plate 6. A pressing piece 23 is provided on the telescopic plate 21 and the telescopic sleeve 22. A groove 24 which is limitedly matched with the pressing piece 23 is opened on the base plate 1. After the pressing piece 23 is separated from the groove 24, the telescopic sleeve 22 is supported on the lower side of the adjusting wheel 11 or the connecting wheel 9.

[0073] The control plate 6 is used to pull the telescopic plate 21 so that the pressing member 23 on the telescopic plate 21 is disengaged from the groove 24, driving the connecting wheel 9 on one side of the control plate 6 to move upward;

[0074] Then pull out the telescopic sleeve 22 to disengage the pressing piece 23 on the telescopic sleeve 22 from the groove 24, adjust the angle of the telescopic sleeve 22, and insert the telescopic sleeve 22 into the lower side of the adjusting wheel 11 or the connecting wheel 9 that needs to be lifted. You can lift the adjusting wheel 11 or the connecting wheel 9 by hand first, and then let go after the telescopic sleeve 22 is inserted into the support, thereby finally driving the machine assembly 2 to move upward, making it easier to repair the bottom of the machine assembly 2.

[0075] In this embodiment, the stabilizing component is correspondingly arranged beside the first pulley 7 which is diagonally related to the control board 6. A plug-in rod 32 is provided at the bottom of the first pulley 7, and the plug-in rod 32 is plugged into the base plate 1. When the movable plate 4 and the fixed plate 5 are lifted, the plug-in rod 32 always maintains a plug-in relationship with the base plate 1;

[0076] It is worth noting that: when the movable plate 4 and the fixed plate 5 are lifted, the adjusting wheel 11 and the connecting wheel 9 are driven to lift, while the first pulley 7 and the second pulley 10 will not lift, the position of the rotating shaft 8 remains unchanged, the connecting wheel 9 is plugged and movable with the rotating shaft 8, the connecting wheel 9 and the rotating shaft 8 are never separated, the adjusting wheel 11 rises, the sliding plate 12 rises, the sliding plate 12 and the second pulley 10 are plugged through the connecting shaft, and the rising sliding plate 12 will not be separated from the connecting shaft, thereby ensuring the overall lifting of the machine component 2.

[0077] The stabilizing component includes an insert plate 25 that penetrates and cooperates with one of the first pulleys 7, the insert plate 25 is plugged into and cooperates with the base plate 1, a matching plate 26 is rotatably connected to the insert plate 25, an elastic plate 27 and an L-shaped plate 28 are fixedly connected to the top of the insert plate 25, the elastic plate 27 is pressed and cooperated with the belt 3, and the top of the matching plate 26 is pressed and cooperated with the elastic plate 27 and the L-shaped plate 28.

[0078] The stabilizing component also includes a slide rod 29 connected and fixed to the plug plate 25 , and two sides of the matching plate 26 are provided with slide grooves 30 slidably matched with the slide rod 29 , and the base plate 1 is provided with a limiting groove 31 slidably matched with the bottom of the matching plate 26 .

[0079] One end of the slide rod 29 located in the slide groove 30 is provided with a circular axis, and the matching plate 26 rotates around the circular axis.

[0080] When the machine assembly 2 needs to be disassembled, that is, the screw compressor, the evaporator, the condenser, the oil-liquid separator, the filter and the cooling box are separated from each other, the plug plate 25 is first lifted upward to separate the plug plate 25 from the base plate 1, and the elastic plate 27 is moved upward away from the belt 3;

[0081] After the repair and replacement work is completed, the movable control plate 6 is used to bring the machine components 2 closer to each other and fit them firmly; and then the first pulley 7 and the belt 3 are fixed again through the plug plate 25.

[0082] It is worth noting that during the fixing process of the plug plate 25, it is only necessary to align the matching plate 26 with the limiting groove 31 so that the position of the plug plate 25 can correspond to the position of the slot on the base plate 1, and then the bottom of the matching plate 26 slides along the limiting groove 31 to press the plug plate 25 down and insert it into the slot on the base plate 1.

[0083] The bottom of the matching plate 26 is made to slide along the direction of the limiting groove 31. The inclined matching plate 26, on the one hand, drives the plug plate 25 to move downward, and makes the plug plate 25 accurately plugged and fixed with the base plate 1, ensuring that the first pulley 7 is stable and does not rotate. On the other hand, the matching plate 26 is tilted to press the elastic plate 27, so that the elastic plate 27 (the elastic effect is small, the plugging between the plug plate 25 and the base plate 1 is a friction plugging, and the elasticity of the elastic plate 27 will not cause the plug plate 25 to automatically detach from the base plate 1) descending with the plug plate 25 is tilted and tightly pressed against the belt 3, ensuring that the belt 3 does not rotate.

[0084] When the top of the matching plate 26 moves to the bottom position, the matching plate 26 presses against the elastic plate 27 on the one hand, and presses against the L-shaped plate 28 on the other hand to ensure a stable pressing effect, wherein there is friction sliding between the bottom of the matching plate 26 and the limiting groove 31.

[0085] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0086] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
