Description

Technical Field

[0001] The utility model relates to the field of high-rise building water supply, in particular to a pump-in-pipe relay water supply device for super high-rise buildings. Background Art

[0002] Super high-rise buildings generally refer to buildings with more than 40 floors or buildings with a height of more than 100 meters. Due to their relatively high building heights, the existing tap water pressure is difficult to meet the water supply needs of the middle and upper buildings of super high-rise buildings. For this reason, the middle part of super high-rise buildings will mostly be equipped with corresponding relay water supply equipment to boost the water supply of the middle and upper buildings of super high-rise buildings. The existing relay water supply equipment for super high-rise buildings generally includes a pipe pump installed in the equipment installation room, and the water inlet and outlet ends of the pipe pump are respectively connected to the water supply pipeline to relay and boost the water supply. Most of the existing pipe-in-pipe pumps have an integrated cavity inside the pump body for installing a submersible motor, and the cavity is provided with a communication channel connected to the outside. However, the integrated design may result in the need to replace the entire pipe-in-pipe pump when the submersible motor fails, resulting in insufficient water supply pressure and affecting the water supply efficiency, so the maintenance cost is relatively high. In addition, in the case of super-high-rise buildings using pipe-in-pipe relay water supply, when the water supply pressure of the pipe-in-pipe pump on a certain floor is insufficient, all floors above it will be affected. It is relatively important to quickly, conveniently and at a low cost to maintain and replace the pipe-in-pipe relay water supply system in super-high-rise buildings.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: a pipe pump relay water supply equipment for super high-rise buildings, including a plurality of pump bodies 1 distributed side by side, the water inlet at the bottom end of each pump body 1 is connected to the water inlet pipeline connecting pipe 2, the water outlet at the top end of each pump body 1 is connected to the water outlet pipeline connecting pipe 3, both ends of each pump body 1 are fixedly connected to the mounting part 4, each pump body 1 includes a pump body shell 101, a water-proof mounting part 102 is arranged inside the pump body shell 101, the water-proof mounting part 102 is coaxially arranged with the pump body shell 101, and the outer wall of the water-proof mounting part 102 is connected to the pump body There is a gap between the inner walls of the outer shell 101, and a dynamic water suction component is installed in the water-proof mounting part 102. A number of connecting blocks 107 evenly distributed in a ring shape are arranged on the outer wall of the water-proof mounting part 102. A limiting hole 108 is formed on the surface of each connecting block 107 facing the inner wall of the water-proof mounting part 102. A connecting screw 109 is provided on the outer wall of the pump body outer shell 101 corresponding to each limiting hole 108. A limiting bolt 110 is threadedly connected to each connecting screw 109, and one end of each limiting bolt 110 is inserted into the corresponding limiting hole 108.

[0022] See also Figure 3 The powered water suction assembly includes a submersible motor 104, which is fixedly connected to the inside of a water-proof mounting portion 102. A mounting hole 103 is provided on the bottom surface of the water-proof mounting portion 102. A rotating shaft 105 is rotatably installed in the mounting hole 103. One end of the rotating shaft 105 extends into the inside of the water-proof mounting portion 102 and is fixedly connected to one end of the output shaft of the submersible motor 104. A plurality of impellers 106 are fixedly sleeved on the portion of the rotating shaft 105 located outside the water-proof mounting portion 102.

[0023] When the submersible motor 104 is started to drive the rotating shaft 105 to rotate, all the impellers 106 rotate independently inside the pump casing 101, thereby generating a low-pressure area inside the pump casing 101, and the water in the water inlet pipe connecting pipe 2 rises from the high-pressure area to the low-pressure area, and then enters the water outlet pipe connecting pipe 3 through the pump casing 101. By arranging a pipe pump on each floor of a high-rise building, water supply can be achieved by relaying water from floor to floor, thereby ensuring the water supply pressure.

[0024] See also Figures 3 to 5The top surface of the water-proof mounting portion 102 is connected to one end of a communication tube 111, and a communication hole 112 is provided on the outer wall of the pump body shell 101 corresponding to the other end of the communication tube 111. A docking tube 113 is provided in the communication hole 112, and a thread 114 is provided on the outer wall of one end of the docking tube 113, and is threadedly connected to the communication hole 112 through the thread 114.

[0025] The communication tube 111 is used to extend the communication cable of the submersible motor 104. When the waterproof mounting part 102 is installed as a whole, the communication cable of the submersible motor 104 extends from one end of the communication tube 111 to the docking tube 113, and extends to the external connection circuit and controller of the pump body casing 101 through the docking tube 113. When disassembling the waterproof mounting part 102 as a whole, the docking tube 113 is rotated to make it independently displaced relative to the waterproof mounting part 102 in the communication hole 112, thereby completing the insertion and separation of the docking tube 113 and the communication tube 111. The separate communication channel can ensure that the waterproof mounting part 102 as a whole can be separated from the pump body casing 101, so as to achieve rapid replacement and installation of the waterproof mounting part 102 and its internal power water absorption component.

[0026] Furthermore, the outer wall diameter of the butt joint pipe 113 is consistent with the inner wall diameter of the limiting ring 115 , and a limiting ring 115 is provided on the outer wall of one end of the butt joint pipe 113 close to the communication pipe 111 .

[0027] The consistent diameter of the outer wall of the docking tube 113 and the inner wall of the communication tube 111 can ensure the sealing after the two are plugged in and connected, reducing the impact of moisture on the communication cable of the submersible motor 104. At the same time, the limit ring 115 can limit the displacement distance of the docking tube 113 to both sides, preventing the docking tube 113 from detaching from the communication hole 112 or being over-inserted into the communication tube 111.

[0028] Furthermore, a groove is provided on the inner wall of the pump housing 101 at one end of the communication hole 112 , and a sealing pad seat 116 is fixedly connected in the groove.

[0029] The sealing pad seat 116 can improve the sealing performance at the communication hole 112, reduce the occurrence of water leakage, and improve the stability during use.

[0030] Furthermore, the thickness of the connection block 107 is consistent with the width of the gap between the outer wall of the water-proof mounting portion 102 and the inner wall of the pump body shell 101.

[0031] The thickness of the connecting block 107 being consistent with the gap width can ensure that the entire connecting spiral tube 109 will not be exposed to moisture passing through the gap, reducing the degree of corrosion of the connecting spiral tube 109 and thus improving the connection stability and overall service life to a certain extent.

[0032] Furthermore, a rubber pad is provided on the surface of the connecting block 107 facing the inner wall of the pump housing 101 .

[0033] Providing a rubber pad on the surface of the connecting block 107 facing the inner wall of the pump body casing 101 can reduce the vibration of the watertight mounting part 102 caused by the submersible motor 104 during operation, thereby reducing the friction between the connecting block 107 and the pump body casing 101, thereby reducing the wear and noise of the inner wall of the pump body casing 101, and at the same time can also improve the sealing of the connecting screw 109, further improving the overall sealing.

[0034] Working principle: When the submersible motor 104 in the pipe pump fails and causes insufficient water supply pressure to affect the water supply efficiency, the corresponding section of the water channel can be temporarily closed, the corresponding pump body 1 can be removed from between the water inlet pipe connecting pipe 2 and the water outlet pipe connecting pipe 3, all the limit bolts 110 can be removed, and the docking pipe 113 can be rotated to move it to the outside of the pump body shell 101 to disengage it from the connection with one end of the communication pipe 111, and the waterproof installation part 102 can be pulled out, and the new waterproof installation part 102 and the power water absorption component can be replaced. First, the positions of all the limit holes 108 are matched one by one with the positions of the connecting screw tube 109, and then all the limit bolts 110 are installed in the connecting screw tube 109. One end of each limiting bolt 110 is inserted into the corresponding limiting hole 108 to complete the limiting of the water-proof installation part 102, and then the connecting pipe 113 is rotated in the opposite direction to allow it to move toward the inside of the pump body shell 101 so that one end of it is again inserted into the inner wall of one end of the communication pipe 111, and the communication cable of the submersible motor 104 is led from the connecting pipe 113 to the outside of the pump body shell 101, and the pump body 1 is connected and installed as a whole back between the water inlet pipe connecting pipe 2 and the water outlet pipe connecting pipe 3, and the communication cable of the submersible motor 104 is connected to the external circuit and controller, so that maintenance and replacement can be completed in a relatively short time, while reducing maintenance costs, and the installation and disassembly process is also relatively simple and convenient.

[0035] It should be noted that the specific model and specifications of the submersible motor 104 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0036] The power supply and principle of the submersible motor 104 are clear to those skilled in the art and will not be described in detail here.

[0037] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
