Description

Technical Field

[0001] This invention relates to the field of water supply equipment technology, and specifically to a water supply equipment with antifreeze function. Background Technology

[0002] Water supply engineering is a project that supplies water for domestic and industrial use to water-using units. The task of water supply engineering is to supply water for cities and residential areas, industrial enterprises, railway transportation, agriculture, construction sites and military use, and to ensure that the above users meet the requirements of water quantity, water quality and water pressure. At the same time, it is also responsible for fire protection in the water-using areas. The function of water supply engineering is to collect natural surface water or groundwater, treat it to meet the water quality standards for industrial production water and residential drinking water, and transport it to various users using economical and reasonable distribution methods. The composition of water supply engineering can be divided into three parts: (1) water intake engineering, which studies the selection of water sources and the correct methods and structures for collecting natural water; (2) water purification engineering, which studies the use of various water treatment methods and structures under different raw water quality and different user requirements for water quality; (3) water transmission and distribution engineering, which studies how to distribute water from the treatment site to various users under economical, safe and reliable conditions. Water supply engineering plays an important role in the construction and development of industry and agriculture, in improving people's material and cultural life, and in the protection of health and safety.

[0034] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] See attached document Figure 1-12 The present invention provides a water supply device with antifreeze function, comprising a protective shell 1, a flow tube 17 inside the protective shell 1, both ends of the flow tube 17 penetrating the protective shell 1, a U-shaped water pipe 25 fixedly connected to the top of the flow tube 17, an antifreeze mechanism on one side of the U-shaped water pipe 25, reciprocating screws 11 on both sides inside the protective shell 1, the top ends of the two reciprocating screws 11 being connected to the top of the inner cavity of the protective shell 1 via bearings, one end of one of the reciprocating screws 11 extending out of the protective shell 1, and a first motor 2 fixedly connected to the top of the protective shell 1. The output end of motor 2 is fixedly connected to one of the reciprocating lead screws 11. Sliding blocks 15 are sleeved on the outside of both reciprocating lead screws 11. The reciprocating lead screws 11 and the sliding blocks 15 are connected by ball nut pairs. Two connecting base plates 16 are fixedly connected to the inside of the protective shell 1. The connecting base plates 16 are connected to the reciprocating lead screws 11 by bearings. Limiting rods 10 are fixedly connected to the top of the two connecting base plates 16. The two limiting rods 10 pass through the two sliding blocks 15 respectively and are fixedly connected to the top of the inner cavity of the protective shell 1. A first buckle assembly is provided on one side of each of the two sliding blocks 15.

[0036] The antifreeze mechanism includes a connecting shell 37, which is located on one side of the U-shaped water pipe 25. Two side plates 36 are fixedly connected to one side of the connecting shell 37, and heating plates 34 are embedded inside each of the two side plates 36. A sliding assembly is provided inside the connecting shell 37, comprising two second telescopic rods 44. Both second telescopic rods 44 are fixedly connected to the inner wall of the connecting shell 37, and first springs 43 are fixedly sleeved on the outside of each of the two second telescopic rods 44. A connecting base 42 is fixedly connected to one side of each of the two second telescopic rods 44. Each of the connecting bases 42 has a movable wheel 33 connected to its inner side via a bearing. The movable wheel 33 contacts the U-shaped water pipe 25. A T-shaped block 38 is fixedly connected to one side of the connecting shell 37. A second buckle assembly is provided on one side of the T-shaped block 38. Limiting rings 35 are fixedly connected to one side of each of the two side plates 36. Two sliding rods 24 are fixedly connected inside the protective shell 1. The two sliding rods 24 pass through the two limiting rings 35 respectively. Pulleys 45 are fixedly sleeved on the outside of each of the two reciprocating screws 11. Belts 46 are sleeved on the outside of the two pulleys 45.

[0037] In this embodiment, the first motor 2 is started, which drives the reciprocating lead screw 11 to rotate. The reciprocating lead screw 11 rotates, which in turn drives the pulley 45 to rotate. The pulley 45 rotates, which in turn drives the belt 46 to rotate. The belt 46 rotates, which in turn drives the pulley 45 outside the other reciprocating lead screw 11 to rotate, causing both reciprocating lead screws 11 to rotate simultaneously. Since the sliding block 15 is limited by the limiting rod 10, the simultaneous rotation of the two reciprocating lead screws 11 drives the sliding block 15 to rotate. The two sliding blocks 15 move upward, which in turn drives the bottom locking block 20 to move upward. Block 20 moves upward and drives H-shaped locking block 40 to move upward. The two H-shaped locking blocks 40 move upward and drive T-shaped block 38 and connecting shell 37 to move upward. This causes connecting shell 37 to drive side plate 36 to move, which in turn drives heating plate 34 to move. This causes the two heating plates 34 to heat U-shaped water pipe 25, melting the ice water inside. Moving wheel 33 reduces friction with U-shaped water pipe 25. First spring 43 and second telescopic rod 44 facilitate turning of U-shaped water pipe 25 at its curved points. Sliding rod 24 and limiting ring 35 are used together to limit movement.

[0038] To achieve the transmission purpose, the device adopts the following technical solution: A transmission mechanism is provided on one side of the protective shell 1. The transmission mechanism includes a second motor 55, which is fixedly installed on one side of the protective shell 1. A transmission shaft 26 is fixedly connected to the output end of the second motor 55. The transmission shaft 26 extends into the interior of the protective shell 1 and is connected to the side wall of the protective shell 1 through a bearing. A connecting block 22 is fixedly connected to one end of the transmission shaft 26. A first telescopic rod 21 is fixedly connected to one side of the connecting block 22. A fixing component is provided on one side of the first telescopic rod 21. When the heating plate 34 rises to the arc surface at the top of the U-shaped water pipe 25, the first motor 2 stops starting. At this time, the second motor 55 is started, causing the second motor 55 to drive the transmission shaft 26 to rotate. The rotation of the transmission shaft 26 drives the connecting block 22 to rotate. The rotation of the connecting block 22 drives the first telescopic rod 21 to rotate. The rotation of the first telescopic rod 21 drives the L-shaped connecting plate 12 to rotate.

[0039] To achieve the snap-fit ​​purpose, this device employs the following technical solution: The first snap-fit ​​assembly includes a bottom snap-fit ​​block 20, inside which a second through groove 52 is formed. A middle plate 56 is fixedly connected inside the second through groove 52. Third telescopic rods 54 are fixedly connected to both sides of the middle plate 56. A third spring 53 is fixedly sleeved on the outside of each third telescopic rod 54. A movable snap-fit ​​block 57 is fixedly connected to one end of each third telescopic rod 54, extending out of the second through groove 52. The third telescopic rod 54 and the third spring 53 are both located inside the second through groove 52. The second snap-fit ​​assembly includes an H-shaped snap-fit ​​block 40, which is fixedly connected to a T-shaped block 38. A snap-fit ​​groove 41 is formed on one side of the H-shaped snap-fit ​​block 40. Four snap-fit ​​units are provided on the outside of the H-shaped snap-fit ​​block 40. Each snap-fit ​​unit includes a first through groove 51, which is formed on one side of the H-shaped snap-fit ​​block 40. The first through groove 51 contains... A pressure plate 50 is provided, and a fixing rod 48 is fixedly connected to one side of the pressure plate 50. A push plate 39 is fixedly connected to one side of the fixing rod 48. One side of the push plate 39 extends out of the outside of the first through groove 51. A fixing plate 47 is fixedly connected inside the first through groove 51. A second spring 49 is sleeved on the outside of the fixing rod 48. The two ends of the second spring 49 are fixedly connected to the fixing plate 47 and the pressure plate 50, respectively. When the push plate 39 moves, it pushes the fixing rod 48 to move. The fixing rod 48 pushes the pressure plate 50 to move, causing the pressure plate 50 to push the first through groove 51 to move. The first through groove 51 moves and enters the second through groove 52, so that the bottom locking block 20 is no longer stuck. When the push plate 39 is no longer squeezed, the second spring 49 rebounds, causing the pressure plate 50 to retract into the first through groove 51. At the same time, the first through grooves 51 on both sides of the bottom locking block 20 on the other sliding block 15 will also be pushed out by the third spring 53 and enter the first through groove 51, so that the bottom locking block 20 locks the antifreeze mechanism.

[0040] To achieve the fixing purpose, this device adopts the following technical solution: The fixing component includes an L-shaped connecting plate 12, which is fixedly connected to the first telescopic rod 21. A U-shaped plate 13 is fixedly connected to one side of the L-shaped connecting plate 12. A servo motor 28 is fixedly mounted on one side of the U-shaped plate 13. A lead screw 30 is fixedly connected to the output end of the servo motor 28. The lead screw 30 passes through the U-shaped plate 13 and is connected to both sides of the U-shaped plate 13 through bearings. Clamping plates 29 are fitted on both outer sides of the lead screw 30. The lead screw 30 and the clamping plates 29 are connected by threads, with the threads on both outer sides of the lead screw 30 having opposite directions. Clamping blocks 31 are fixedly connected to one side of each of the two clamping plates 29. The inner side of the U-shaped plate 13 is fixedly connected to... A limiting crossbar 32 is connected, which passes through two clamping plates 29 and is slidably connected to the clamping plates 29. A connecting shaft 27 is fixedly connected to one side of the L-shaped connecting plate 12. A pulley 23 is connected to one end of the connecting shaft 27 through a bearing. A sliding groove 18 is opened on the inner side wall of the protective shell 1. The pulley 23 extends into the sliding groove 18. When the servo motor 28 is started, the servo motor 28 drives the lead screw 30 to rotate. Since the clamping plate 29 is limited by the limiting crossbar 32, the lead screw 30 drives the clamping plate 29 to move towards the middle, so that the clamping plate 29 drives the clamping block 31 to move and the clamping block 31 enters the clamping groove 41. At the same time, the clamping plate 29 contacts the push plate 39. The pulley 23 on one side of the L-shaped connecting plate 12 slides in the sliding groove 18 to prevent the connecting shell 37 from detaching.

[0041] To achieve the purpose of water supply, this device adopts the following technical solution: one end of the flow pipe 17 is fixedly connected to the inlet pipe 5, one end of the inlet pipe 5 is fixedly connected to the first water storage tank 6, a connecting valve 4 is fixedly installed on one side of the inlet pipe 5, a connecting pipe 3 is fixedly connected to one side of the connecting valve 4, one end of the connecting pipe 3 is fixedly connected to the second water storage tank 9, and one side of the second water storage tank 9 is fixedly connected to the outlet pipe 8. One end of the outlet pipe 8 is fixedly connected to the other end of the flow pipe 17. The elevation difference between the first water storage tank 6, the second water storage tank 9, and the U-shaped water pipe 25 forms a circulating loop in the pipeline between the first water storage tank 6, the U-shaped water pipe 25, and the second water storage tank 9, so that the water in the pipeline can always be in a flowing state, thereby realizing the circulation of water in the water supply pipe above the frozen soil layer and achieving the purpose of antifreeze. Since the altitude of the second water storage tank 9 is higher than that of the U-shaped water pipe 25, in the case of insufficient water supply, the water supply demand can still be guaranteed by adjusting the second water storage tank 9 through the connecting valve 4, ensuring normal water supply.

[0042] To achieve the purpose of heat preservation, the device adopts the following technical solution: a connecting bend 19 is fixedly connected to one side of the U-shaped water pipe 25, one end of the connecting bend 19 extends out of the protective shell 1, and a water tap 7 is fixedly connected to one end of the connecting bend 19. Insulation plates 14 are provided on both sides of the U-shaped water pipe 25, and the insulation plates 14 are fixedly connected to the bottom of the inner cavity of the protective shell 1. The insulation plates 14 have the function of heat preservation.

[0043] The usage process of this invention is as follows: When using this invention, when the temperature reaches below zero, the water in the U-shaped water pipe 25 becomes a mixture of crushed ice and water. At this time, the heating plate 34 begins to heat up to a certain temperature, starting the first motor 2. The first motor 2 starts and drives the reciprocating screw 11 to rotate. The reciprocating screw 11 rotates and drives the pulley 45 to rotate. The pulley 45 rotates and drives the belt 46 to rotate. The belt 46 rotates and drives the pulley 45 outside the other reciprocating screw 11 to rotate, causing the two reciprocating screws 11 to rotate simultaneously. Since the sliding block 15 is limited by the limiting rod 10, the two reciprocating screws 11 rotate simultaneously and drive the sliding block 15 to rotate. The two sliding blocks 15 move upward and drive the bottom locking block 20 to move upward. The bottom locking block 20 moves upward, causing the H-shaped locking block 40 to move upward. The two H-shaped locking blocks 40 move upward, causing the T-shaped block 38 and connecting shell 37 to move upward. This causes the connecting shell 37 to move the side plate 36, which in turn moves the heating plate 34. The two heating plates 34 then heat the U-shaped water pipe 25, melting the ice water inside. When the heating plate 34 rises to the top arc-shaped surface of the U-shaped water pipe 25, the first motor 2 stops. At this time, the second motor 55 starts, causing the transmission shaft 26 to rotate. The rotation of the transmission shaft 26 causes the connecting block 22 to rotate, which in turn causes the first telescopic rod 21 to rotate. The rotation of the first telescopic rod 21 then causes the L-shaped connecting plate 12 to rotate. The L-shaped connecting plate 12 rotates, causing the U-shaped plate 13 to rotate as well, positioning the H-shaped locking block 40 between the two locking plates 29. At this point, the servo motor 28 is activated, driving the lead screw 30 to rotate. Because the locking plate 29 is limited by the limiting crossbar 32, the lead screw 30 causes the locking plate 29 to move towards the center, moving the locking block 31 into the slot 41. Simultaneously, the locking plate 29 contacts the push plate 39, causing it to move. The push plate 39 moves and pushes the fixing rod 48, which in turn pushes the pressure plate 50, causing it to move the first through slot 51. The first through slot 51 moves and enters the second through slot 52, freeing the bottom locking block 20 from being locked. Simultaneously, the locking plate 29 and the locking block 31... The H-shaped locking block 40 is positioned. The second motor 55 is then activated again, causing the transmission shaft 26 to rotate. The transmission shaft 26 rotates the connecting block 22, which in turn rotates the first telescopic rod 21. This causes the connecting block 22 to move the fixing assembly. Simultaneously, the pulley 23 on one side of the L-shaped connecting plate 12 slides within the sliding groove 18, preventing the connecting shell 37 from disengaging. This causes the fixing assembly to rotate 180 degrees. At this point, the top of the original H-shaped locking block 40 flips and reaches the top of another sliding block 15. The servo motor 28 is then activated, causing the lead screw 30 to reverse, releasing the H-shaped locking block 40 from the locking plate 29. The push plate 39 is no longer compressed, and the second spring 49 rebounds, causing the pressure plate 50 to retract into the first through groove 51.Simultaneously, the first through slots 51 on both sides of the bottom locking block 20 on one side of the other sliding block 15 will also be pushed out by the third spring 53 and enter the first through slot 51, causing the bottom locking block 20 to lock the antifreeze mechanism. At this time, the first motor 2 continues to start, causing the reciprocating screw 11 to rotate and drive the sliding block 15 to descend. After the heating plate 34 heats the bent part, it heats the vertical part of the U-shaped water pipe 25 again, repeating this several times to prevent the water in the U-shaped water pipe 25 from freezing. The insulation plate 14 can keep the temperature and reduce heat loss. At the same time, the first The elevation difference between the first reservoir 6, the second reservoir 9, and the U-shaped water pipe 25 creates a circulating loop in the pipeline connecting the first reservoir 6, the U-shaped water pipe 25, and the second reservoir 9. This ensures that the water in the pipeline remains constantly flowing, allowing for water circulation in the water supply pipes above the frost line and achieving antifreeze protection. Because the second reservoir 9 is at a higher elevation than the U-shaped water pipe 25, even with insufficient water supply, adjusting the second reservoir 9 via the connecting valve 4 can still guarantee water supply and ensure normal operation.
