Description

Technical Field

[0001] The utility model relates to the field of water pump equipment, in particular to an automatic constant pressure water pump. Background Art

[0002] An automatic constant pressure water pump is a pump that can automatically adjust the water supply pressure according to the system demand. Its working principle is based on a negative feedback control system, and the speed of the motor is adjusted through electronic frequency conversion technology to achieve a constant water supply pressure.

[0003] In the actual application of the automatic constant pressure water pump, it mainly depends on the efficient and stable transportation of water from the source to each water use point through the conveying pipeline. However, natural water bodies often contain various impurities, including but not limited to fine sediment particles, microorganisms, and dissolved or suspended organic matter, etc. When these impurities flow through the automatic constant pressure water pump with the water flow, they may be sucked into the pump body. After long-term accumulation, it will not only affect the operation efficiency of the water pump, but also may cause wear or blockage to the internal components of the water pump. Therefore, before the water enters the water pump, in order to reduce the chance of them entering the water pump interior while also facilitating the subsequent cleaning work, an automatic constant pressure water pump is proposed.

[0034] Please refer to Figure 1 - Figure 6 , an automatic constant pressure water pump, including a constant pressure water pump body 1 with a conveying pipeline 101. The openings at both ends of the conveying pipeline 101 are provided with co-directional built-in cylinders 2, and the built-in cylinders 2 are provided with detachable intercepting mesh plates 3 for collection.

[0035] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, the automatic constant-pressure water pump of the present application is mainly composed of a constant-pressure water pump body 1, a conveying pipeline 101 and other structures. The two ends of the conveying pipeline 101 are provided with openings for connecting to complete the water conveyance. At this time, an inner cylinder 2 with the same direction is arranged inside the conveying pipeline 101, and the inner cylinder 2 is used for collecting the intercepted impurities during the conveying process. The inner cylinder 2 is provided with an intercepting mesh plate 3. When water passes through the opening of the conveying pipeline 101 and flows from the inner cylinder 2 to the connecting cylinder opening 201, several holes are arranged on the intercepting mesh plate 3 to intercept large impurities while ensuring the water flow rate. A filter layer is laid inside the connecting cylinder opening 201 to further intercept impurities in the water, so as to reduce the chance of impurities in the water entering the constant-pressure water pump body 1. It is convenient to intercept when the water source passes, and the opening design also facilitates subsequent disassembly and cleaning, so as to ensure the overall use effect of the device.

[0036] In the present application, a connecting cylinder opening 201 is also provided. The inner cylinder 2 and the connecting cylinder opening 201 are designed as an integral structure. The connecting cylinder opening 201 supports the inner cylinder 2 in the openings at both ends of the conveying pipeline 101, so that when water flows through, interception operations can be directly carried out. The inner end of the connection between the two has a radian to facilitate guiding operations when water flows from the connecting cylinder opening 201 into the inner part of the inner cylinder 2.

[0037] In the present application, a sealing ring 7 and a positioning ring opening 701 are also provided. A groove is provided on the outer circle of the connecting cylinder opening 201. This groove can make the sealing ring 7 sleeved thereon, and after sleeving, it protrudes from the outer wall of the connecting cylinder opening 201. When the connecting cylinder opening 201 contacts the inner wall of the conveying pipeline 101, an interaction force can be generated between the protruding part of the connecting cylinder opening 201 and the inner wall of the conveying pipeline 101. The sealing ring 7 is designed with a rubber material to improve the sealing performance of the connection while ensuring the water flow; the positioning ring opening 701 is made of a hard material and is glued to both ends of the sealing ring 7. When the sealing ring 7 is sleeved in the groove of the connecting cylinder opening 201, the positioning ring opening 701 closely fits on the outer wall of the connecting cylinder opening 201 to further position the sealing ring 7 during installation.

[0038] In the present application, a connecting cylinder part 301 is also provided. The intercepting mesh plate 3 is fixedly connected inside the connecting cylinder part 301. After the connecting cylinder part 301 is rotated into the opening of the inner cylinder 2, threads matching the outer wall of the intercepting mesh plate 3 are provided on the inner wall of the inner cylinder 2. Then, the intercepting mesh plate 3 can be threadedly connected to the inside of the inner cylinder 2 by rotation. In this way, while assembling the intercepting mesh plate 3 and the inner cylinder 2, it is also convenient to replace the overall structure of the intercepting mesh plate 3 according to the usage requirements.

[0039] A sealing ring 4 is also provided in this application. The sealing ring 4 is arranged between the connecting cylinder part 301 and the built-in cylinder 2. When the connecting cylinder part 301 is rotated into the interior of the built-in cylinder 2, its external protruding part restricts it at the opening of the built-in cylinder 2, and the sealing ring 4 arranged therebetween can improve the sealing effect of the connection between the two.

[0040] It should also be noted that one end of the sealing ring 4 is clamped on the protruding part outside the connecting cylinder part 301. When the connecting cylinder part 301 is rotated into the interior of the built-in cylinder 2, the other end of the sealing ring 4 can be tightly pressed against the opening of the built-in cylinder 2, so as to ensure the stability of the sealing ring 4 during application.

[0041] A limiting inner frame 5 and a stabilizing convex ring 501 are also provided in this application. The limiting inner frame 5 is fixedly installed at the corresponding position on the inner wall of the built-in cylinder 2. When the connecting cylinder part 301 is rotated into the interior of the built-in cylinder 2, one end of it can be inserted into the interior of the limiting inner frame 5, so as to perform a limiting operation on the overall structure of the connecting cylinder part 301 during installation; when one end of the connecting cylinder part 301 is inserted into the interior of the limiting inner frame 5, a stabilizing convex ring 501 is adhesively bonded to the inner wall of the limiting inner frame 5. The stabilizing convex ring 501 is designed with a rubber material, which can make the contact between the connecting cylinder part 301 and the limiting inner frame 5 closer, so as to improve the stability of the connection part.

[0042] A supporting and fixing sleeve 6, a magnetic attracting cylinder mouth 601 and a magnetic attracting convex layer 302 are also provided in this application. Among them, the supporting and fixing sleeve 6 and the magnetic attracting cylinder mouth 601 are of an integral structure design. The supporting and fixing sleeve 6 is respectively located in the conveying pipeline 101 and can match the corresponding built-in cylinder 2 at one end. The supporting and fixing sleeve 6 is connected to the thread provided on the inner wall of the conveying pipeline 101 by rotation. The supporting and fixing sleeve 6 is completely connected in the conveying pipeline 101 according to the installation position of the built-in cylinder 2. When the whole supporting and fixing sleeve 6 is positioned inside the conveying pipeline 101, the magnetic attracting cylinder mouth 601 restricts the built-in cylinder 2 at the corresponding position inside the constant pressure water pump body 1. At the same time, a magnetic attracting convex layer 302 is connected to the protruding part of the connecting cylinder part 301. When the built-in cylinder 2 is restricted, a magnetic attracting connection can be generated between the magnetic attracting cylinder mouth 601 and the magnetic attracting convex layer 302, so as to improve the stability of the connection at the restricted part.
