[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments 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 some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0027] Please refer to Figures 1-4 As shown, the integrated river water intake device includes a cabinet body 10, a buffer water tank 11, a filtering tank 12, a water intake pump 13, and a walking wheel set 14. The cabinet body 10 can be divided into an upper installation cavity 15, a middle installation cavity 16, and a lower installation cavity 17 from top to bottom by a partition board. The upper installation cavity 15, the middle installation cavity 16, and the lower installation cavity 17 are designed to have different sizes according to different installation needs. Among them, the filtering tank 12 and the buffer water tank 11 are arranged in the lower installation cavity 17, and the filtering tank 12 and the buffer water tank 11 are distributed on both sides of the installation cavity. The filtering tank 12 and the buffer water tank 11 are made of stainless steel boxes. The buffer water tank 11 is designed as a circular tank shape to have good pressure-bearing capacity. The volume in the buffer water tank 11 is larger than the volume in the filtering tank 12. The water intake pump 13 is arranged in the middle installation cavity 16 and is used to send the water in the buffer water tank 11 to the water distributor of the water source heat pump system for the use of the water source heat pump unit. The upper installation cavity 15 is an electrical installation space for installing power supply wiring and related control components for controlling the device. The walking wheel set 14 is detachably assembled under the cabinet body 10. For example, when the device needs to be moved, the walking wheel set 14 can be installed under the cabinet body 10 so that the cabinet body 10 can move under the push of an external force. When the cabinet body 10 moves to the place, the walking wheel set 14 can be disassembled to avoid damaging the walking wheel set 14 due to the increased weight of the cabinet body 10 during the water intake process, resulting in heavy load on the walking wheel set 14.

[0028] One side of the bottom of the filtering tank 12 is connected to a water intake pipe 18. One end of the water intake pipe 18 extends from inside the cabinet 10 to the outside of one side of the cabinet 10 and is used to form a connection with a river water pipe extending into the river water. An underwater filter can be installed at the front end of the river water pipe to filter out debris in the water, and then it is sent into this device through the water intake pipe 18. The other end of the water intake pipe 18 is connected to the bottom of the filtering tank 12, and the river water enters the filtering tank 12 from the bottom through the water intake pipe 18. It can also be designed that the filtering tank 12 adopts an internal circular cavity structure, and the water intake pipe 18 is connected to the inner cavity of the filtering tank 12 in an inner cavity connection mode. In this way, the water sent into the filtering tank 12 by the water intake pipe 18 forms a swirling flow in the filtering tank 12, reducing the probability of small particles contained in the water flowing upward, and is filtered by the filter body at the bottom of the filtering tank 12. A first control valve 19 is installed on the water intake pipe 18 to control the water entering the water intake pipe 18 to enter the filtering tank 12.

[0029] The buffer water tank 11 and the filtering tank 12 are connected through an intermediate pipe 20. A second control valve 21 is installed on the intermediate pipe 20 to control the water in the filtering tank 12 to enter the buffer water tank 11. That is, when the device is taking water, the second control valve 21 is opened, and the water in the filtering tank 12 can enter the buffer water tank 11 through the intermediate pipe 20.

[0030] The inlet of the water intake pump 13 is connected to the inside of the buffer water tank 11 through a connecting pipe 22. The connecting pipe 22 can be connected to the bottom of the buffer water tank 11. A three-way valve 23 is installed at the discharge port of the water intake pump 13. The inlet end of the three-way valve 23 is connected to the discharge port of the water intake pump 13. The first outlet end of the three-way valve 23 is connected to a water supply pipe 24, and the water supply pipe 24 extends to the outside of the cabinet 10. The second outlet end of the three-way valve 23 is connected to the inner top of the filtering tank 12 through a circulating pipe 25. In this way, during the water intake process of the device, the three-way valve 23 is switched so that the discharge port of the water intake pump 13 is connected to the water supply pipe 24, and the discharge port of the water intake pump 13 and the circulating pipe 25 are in a closed state. Thus, the water in the buffer water tank 11 is sent by the water intake pump 13 to the water supply pipe 24 through the connecting pipe 22, and the water supply pipe 24 sends the water into the water distributor of the water source heat pump system.

[0031] A supply and discharge pipe 26 is connected to the bottom of the filtering tank 12 and extends to the outside of the cabinet 10. A third control valve 27 is installed on the supply and discharge pipe 26. When it is necessary to discharge the filter in the bottom of the filtering tank 12, the third control valve 27 can be opened to connect the filtering tank 12 with the supply and discharge pipe 26. In this way, the filter can be discharged outside the cabinet 10, and the supply and discharge pipe 26 can be connected to the connecting pipe 22 and the river channel to discharge the filter into the river channel.

[0032] A first liquid level sensor is provided in the buffer water tank 11, and the first liquid level sensor transmits the detected water level information to the controller of the water intake pump 13; during the water intake process of the device, the first control valve 19 and the second control valve 21 are opened, and the three-way valve 23 is switched so that the water supply pipe 24 is communicated with the discharge port of the water intake pump 13. In this way, the river water forms a flow path through the water intake pipe 18, the filter tank 12, the intermediate pipe 20, the buffer water tank 11, the communication pipe 22, the water intake pump 13, and the water supply pipe 24; when cleaning the bottom of the filter tank 12, by closing the first control valve 19, the second control valve 21, and the communication between the water supply pipe 24 and the discharge port of the water intake pump 13, the third control valve 27 is opened, and the three-way valve 23 is switched so that the discharge port of the water intake pump 13 is communicated with the circulation pipe 25. The water intake pump 13 conveys the water in the buffer water tank 11 into the filter tank 12 through the circulation pipe 25, and the water flows downward in the filter tank 12 and is discharged from the water supply and discharge pipe 26; among them, the first liquid level sensor detects the water level in the buffer water tank 11: one is the low water level value in the buffer water tank 11 to ensure that the communication pipe 22 is below the water level to avoid the occurrence of no-load conditions when the water intake pump 13 is started; the other is to reflect the high water level value in the buffer water tank 11 before cleaning the filter tank 12, that is, only when the water level in the buffer water tank 11 is greater than the high water level value can the cleaning of the filter tank 12 be switched. Therefore, before cleaning the filter tank 12, the water in the water tank needs to be replenished to exceed the high water level value, and the water volume between the low water level value and the high water level value in the buffer water tank 11 is used to clean the filter tank 12 to ensure the sufficiency of the cleaning water. When the low water level value is reached, the cleaning process is stopped.

[0033] An installation cross beam 28 is fixedly arranged at the bottom of the installation cavity 16 in the cabinet body 10. The water intake pump 13 is assembled on the installation cross beam 28 through a buffer assembly to reduce the impact of the vibration of the water intake pump 13 during operation on the cabinet body 10.

[0034] In some embodiments, there are two buffer components, which are distributed between the two ends of the base of the water intake pump 13 and the installation cross beam 28; the buffer component includes a pair of mounting seats 29, a buffer base 30, and a buffer spring 31. The mounting seat 29 is in the shape of a bracket with the upper end extending outwards less than the lower end extending outwards. The pair of mounting seats 29 are arranged back to back, and a buffer space 32 is formed therebetween in an up-and-down arrangement; the buffer base 30 is fixedly assembled at the bottom between the pair of mounting seats 29 (buffer space), and the buffer base 30 can be fixed between the pair of mounting seats 29 by common fixed connection methods such as welding and bolts; the upper part of the pair of mounting seats 29 is elastically connected to the base of the water intake pump 13, and the lower part of the pair of mounting seats 29 is connected to the installation cross beam 28. The buffer spring 31 is arranged above the buffer base 30 and is compressed between the buffer base 30 and the base of the water intake pump 13. That is, during the operation of the water intake pump 13, through the buffering of the buffer spring 31, the vibration generated when the water intake pump 13 is directly assembled in the cabinet 10 can be correspondingly reduced.

[0035] In some embodiments, an annular retaining groove 33 is fixedly arranged on the lower surface of the base of the water intake pump 13. The annular retaining groove 33 is fixedly welded to the lower surface of the base of the water intake pump 13. The annular retaining groove 33 is arranged with the notch facing the buffer base 30. The inner diameter of the inner wall of the annular retaining groove 33 is adapted to the outer diameter of the buffer spring 31. A circular retaining block 34 is fixedly arranged on the upper surface of the buffer base 30. The outer diameter of the outer periphery of the circular retaining block 34 is adapted to the inner diameter of the buffer spring 31. The outer periphery of the upper end of the buffer spring 31 is clamped on the inner wall of the notch of the annular retaining groove 33, and the outer periphery of the lower end of the buffer spring 31 is clamped on the outer periphery of the circular retaining block 34, so as to form constraints on the upper and lower ends of the buffer spring.

[0036] In some embodiments, a rubber buffer pad 35 is arranged between the lower surface of the base of the water intake pump 13 and the upper surface of the mounting seat 29 to improve the buffering ability between the lower surface of the base of the water intake pump 13 and the upper surface of the mounting seat 29.

[0037] In some embodiments, the base of the water intake pump 13 and the upper end of the mounting seat 29 are connected by a connecting bolt 36, and a spring member 37 compressed by the upper surface of the base of the water intake pump 13 and the nut of the connecting bolt 36 is sleeved on the connecting bolt 36, so as to form an elastic connection between the base of the water intake pump 13 and the mounting seat 29.

[0038] In some embodiments, a filter body 38 with a conical cross-section is fixedly welded in the filter tank 12. Filter holes 39 are distributed on the filter body 38. The end with a larger diameter of the filter body 38 is close to the connection between the circulation pipeline 25 and the filter tank 12, and the end with a smaller diameter is close to the connection between the water intake pipeline 18 and the filter tank 12. During cleaning, the water flowing from top to bottom converges towards the middle position of the filter body 38 to clean the space of the filter tank 12 below the filter body 38. The bottom of the filter tank 12 is set as a conical bottom 40 that converges towards the center, so that the water converges towards the supply and discharge pipeline 26, and thus the cleaning effect is better.

[0039] In some embodiments, the connection between the middle pipeline 20 and the filter tank 12 is above the filter body 38, so that the water entering the middle pipeline 20 is filtered by the filter body 38.

[0040] In some embodiments, mounting plates 41 are respectively and fixedly welded at the four corners of the outer periphery below the cabinet body 10. Triangular reinforcing plates 42 are fixedly welded between the upper surface of the mounting plates 41 and the outer wall of the frame of the cabinet body 10 to enhance the connection strength. The traveling wheel set 14 is assembled on the mounting plates 41 through bolts, thus facilitating the installation and disassembly of the traveling wheel set 14.

[0041] Finally, it should be noted that the above embodiments are only relatively preferred embodiments of the present invention to illustrate the technical solutions of the present invention, rather than limiting it, let alone limiting the patent scope of the present invention; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention; in addition, directly or indirectly applying the technical solutions of the present invention to other related technical fields shall also be included in the patent protection scope of the present invention by the same token.
