Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a water suction device of a vacuum water pump. Background Art

[0002] The vacuum water pump is connected to the water suction device. The water suction device with the publication number CN2399534Y in the prior art solves the disadvantages of the traditional water suction device being difficult to install and maintain, but it still has the following disadvantages;

[0003] The volume of the vacuum water storage tank is relatively large, and the vertical cylindrical shape, when the water storage capacity is large, the water flow from top to bottom may cause the water storage tank to shake;

[0004] The water inlet pipe passes through the side of the tank body, and part of the water inlet pipe is placed outside, which not only prolongs the length of the water inlet pipe, but also makes the exposed water inlet pipe likely to be damaged and is not convenient for installation;

[0005] The tank body is completely closed, and several pipe inlets and outlets cannot meet the needs of inspection and cleaning inside the tank body. Utility Model Content

[0006] In order to solve the deficiencies in the prior art, the utility model provides a water suction device for a vacuum water pump. The water suction device for the vacuum water pump greatly enhances its stability by setting a truncated cone or stepped tank structure. The inner arch structure arranged at the bottom of the vacuum water storage tank reduces the internal volume of the tank on the one hand, and provides an installation space for the layout of a water inlet pipe on the other hand. The water inlet pipe is directly inserted from the inner arch into the water pool below the vacuum water storage tank, which is safer and shorter in length. The sealing cover on the top can be opened for water injection, and can also meet the needs of inspection and cleaning of the interior of the tank.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The utility model provides a water absorption device for a vacuum water pump, comprising a vacuum water storage tank, wherein the vacuum water storage tank is in a truncated cone shape or a stepped cone shape, and the bottom surface of the vacuum water storage tank has an inner arch structure facing the inside thereof;

[0009] A water outlet pipe is connected to the bottom of the side of the vacuum water storage tank, a water inlet pipe is passed through the top surface of the inner arch of the vacuum water storage tank, one end of the water inlet pipe extends to the inside of the vacuum water storage tank, and the other end of the water inlet pipe extends to the outside of the bottom of the vacuum water storage tank, and a sealing cover is arranged on the top of the vacuum water storage tank.

[0010] When installing the water suction device of the vacuum water pump of the utility model, the sealing cover is first opened, and the gap at the top of the vacuum water storage tank after the sealing cover is opened is used to pass the water inlet pipe through the water inlet hole on the inner arch surface of the vacuum water storage tank, and the height of the water inlet pipe inside the vacuum water storage tank is adjusted, and then the sealing installation is performed. The vacuum water storage tank is fixed above the underground water pool, so that the outer end of the water inlet pipe extends into the underground water pool, the water outlet pipe is connected to the vacuum water pump, and water is injected through the gap at the top of the vacuum water outlet pipe. After the water injection is completed, the sealing cover is closed and the casing begins to be used.

[0011] The water suction device of the vacuum water pump of the utility model greatly enhances its stability by providing a truncated cone or stepped tank structure. The inner arch structure provided at the bottom of the vacuum water storage tank reduces the internal volume of the tank on the one hand, and provides installation space for the layout of the water inlet pipe on the other hand. The water inlet pipe is directly inserted into the water pool below the vacuum water storage tank from the inner arch, which is safer and shorter in length. The sealing cover on the top can be opened for water injection and can also meet the needs of inspection and cleaning of the interior of the tank.

[0012] In a further technical solution, the water inlet pipe includes an inner water inlet pipe and an outer water inlet pipe. The inner water inlet pipe is installed on the top surface of the inner arch inside the vacuum water storage tank through a mounting plate. One end of the inner water inlet pipe passes through the mounting plate and the inner arch and is connected with a connector. The outer water inlet pipe is connected to the inner water inlet pipe through the connector.

[0013] The water inlet pipe is divided into inner and outer parts, which further facilitates the installation operation, reduces the difficulty of installation, and can be replaced quickly when there is a problem with the pipe.

[0014] In a further technical solution, the inner water inlet pipe is a hard pipe arranged inside the vacuum water storage tank, and the outer water inlet pipe is a corrugated pipe.

[0015] The inner water inlet pipe and the outer water inlet pipe are made of pipes of different materials. The hard inner water inlet pipe has stable water inlet and is highly stable. The outer water inlet pipe is designed as a corrugated pipe, which allows the outer water inlet pipe to move in a certain position in the pool, reducing the stress of the outer water inlet pipe being directly impacted by the water flow and extending its service life.

[0016] In a further technical solution, a stabilizing head is provided at one end of the outer water inlet pipe away from the inner water inlet pipe, and a counterweight is provided inside the stabilizing head.

[0017] The setting of the stabilizing head makes the bottom water inlet position of the external water inlet pipe relatively fixed, ensuring the water inlet effect. It also provides an installation basis for the water inlet filtering mechanism, which is more expandable.

[0018] In a further technical solution, the inner arch is in a truncated cone or a stepped cone shape.

[0019] The inner arch has to withstand greater water pressure inside the vacuum water storage tank and the force brought by the water inlet pipe, so its shape is designed to be a truncated cone or a stepped cone, which improves its structural stability.

[0020] In a further technical solution, a sleeve is provided on the outer sleeve of the inner water inlet pipe, and one end of the sleeve is connected to the mounting plate.

[0021] The setting of the sleeve further improves the structural stability of the inner water inlet pipe, and can evenly transfer the force applied to the inner water inlet pipe to the mounting plate, so that the service life of the inner water inlet pipe is longer and it is less prone to water leakage.

[0022] The beneficial effects are:

[0023] 1. The water suction device of the vacuum water pump of the utility model greatly enhances its stability by setting a truncated or stepped tank structure. The inner arch structure arranged at the bottom of the vacuum water storage tank reduces the internal volume of the tank on the one hand, and provides installation space for the layout of the water inlet pipe on the other hand. The water inlet pipe is directly inserted from the inner arch into the pool below the vacuum water storage tank, which is safer and shorter in length. The cover on the top can be opened for water injection and can also meet the needs of inspection and cleaning of the inside of the tank.

[0024] 2. The water inlet pipe is divided into inside and outside, which further facilitates the installation operation, reduces the difficulty of installation, and can be replaced quickly when there is a problem with the pipeline.

[0025] 3. The inner and outer water inlet pipes are made of different materials. The hard inner water inlet pipe has stable water inlet and is highly stable. The outer water inlet pipe is designed as a corrugated pipe, which allows the outer water inlet pipe to move in a certain position in the pool, reducing the stress of the outer water inlet pipe being directly impacted by the water flow and extending its service life.

[0026] 4. The setting of the stabilizing head makes the bottom water inlet position of the external water inlet pipe relatively fixed, ensuring the water inlet effect. At the same time, it also provides an installation basis for the water inlet filtering mechanism, which is more expandable.

[0027] 5. The inner arch has to withstand greater water pressure inside the vacuum water storage tank and the force brought by the water inlet pipe, so its shape is designed to be a truncated cone or a stepped cone to improve its structural stability.

[0028] 6. The setting of the sleeve further improves the structural stability of the inner water inlet pipe, and can evenly transfer the force applied to the inner water inlet pipe to the mounting plate. The service life of the inner water inlet pipe is longer and it is less prone to water leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The utility model is further described below in conjunction with the accompanying drawings:

[0032] Example:

[0033] A water suction device for a vacuum water pump, such as Figure 1 As shown, it includes a vacuum water storage tank 10, the shape of the vacuum water storage tank 10 is a truncated cone or a stepped cone, and the bottom surface of the vacuum water storage tank 10 has an inner arch 12 structure facing the inside thereof;

[0034] A water outlet pipe 20 is connected to the bottom of the side of the vacuum water storage tank 10, and a water inlet pipe is penetrated through the top surface of the inner arch 12 of the vacuum water storage tank 10. One end of the water inlet pipe extends to the inside of the vacuum water storage tank 10, and the other end of the water inlet pipe extends to the outside of the bottom of the vacuum water storage tank 10. A sealing cover 11 is arranged on the top of the vacuum water storage tank 10.

[0035] It is understandable that the installation structure and installation process of the water outlet pipe 20 and the water inlet pipe are technical means commonly used by technicians in this field, such as the installation structure of a welding flange and a waterproof sealing ring, etc., which will not be repeated here.

[0036] When installing the water suction device of the vacuum water pump of the utility model, the sealing cover 11 is first opened, and the notch at the top of the vacuum water storage tank 10 is used after the sealing cover 11 is opened, and the water inlet pipe is passed through the water inlet hole on the top surface of the inner arch 12 of the vacuum water storage tank 10, and the height of the water inlet pipe inside the vacuum water storage tank 10 is adjusted, and then the sealing installation is performed, and the vacuum water storage tank 10 is fixed above the underground water pool, so that the outer end of the water inlet pipe extends into the underground water pool, the water outlet pipe 20 is connected to the vacuum water pump, and water is injected through the notch at the top of the vacuum water outlet pipe 20. After the water injection is completed, the sealing cover 11 is closed and the casing begins to be used.

[0037] The water suction device of the vacuum water pump of the utility model greatly enhances its stability by setting a truncated cone or stepped tank structure. The inner arch 12 structure set at the bottom of the vacuum water storage tank 10 reduces the internal volume of the tank on the one hand, and provides an installation space for the layout of the water inlet pipe on the other hand. The water inlet pipe is directly inserted from the inner arch 12 into the pool below the vacuum water storage tank 10, which is safer and shorter in length. The sealing cover 11 on the top can be opened for water injection and can also meet the needs of inspection and cleaning of the interior of the tank.

[0038] It is understandable that the volume inside the tank and the volume inside the water inlet pipe need to be calculated to determine the height of the inner arch 12.

[0039] In another embodiment, if Figure 1 As shown, the water inlet pipe includes an inner water inlet pipe 30 and an outer water inlet pipe 40. The inner water inlet pipe 30 is installed on the top surface of the inner arch 12 located inside the vacuum water storage tank 10 through a mounting plate 32. One end of the inner water inlet pipe 30 passes through the mounting plate 32 and the inner arch 12 and is connected to a connector. The outer water inlet pipe 40 is connected to the inner water inlet pipe 30 through the connector.

[0040] The water inlet pipe is divided into inner and outer parts, which further facilitates the installation operation, reduces the difficulty of installation, and can be replaced quickly when there is a problem with the pipe.

[0041] During installation, the inner water inlet pipe 30 is installed first, and then the outer water inlet pipe 40 is connected to the connector extending from the inner water inlet pipe 30 from the outside of the vacuum water storage tank 10, thereby reducing the difficulty of installation.

[0042] In another embodiment, if Figure 1 As shown, the inner water inlet pipe 30 is a hard pipe arranged inside the vacuum water storage tank 10, and the outer water inlet pipe 40 is a corrugated pipe. In this embodiment, the corrugated pipe is a metal bellows.

[0043] The inner water inlet pipe 30 and the outer water inlet pipe 40 are made of pipes of different materials. The hard inner water inlet pipe 30 stably inlets water and is highly stable. The outer water inlet pipe 40 is designed as a corrugated pipe, which allows the outer water inlet pipe 40 to move in a certain position in the pool, reducing the stress on the outer water inlet pipe 40 caused by direct impact of the water flow, and extending its service life.

[0044] In another embodiment, if Figure 1 As shown, a stabilizing head 41 is disposed at one end of the outer water inlet pipe 40 away from the inner water inlet pipe 30 , and a counterweight is disposed inside the stabilizing head 41 .

[0045] The setting of the stabilizing head 41 makes the bottom water inlet position of the external water inlet pipe 40 relatively fixed, ensuring the water inlet effect, and also provides an installation basis for the water inlet filtering mechanism, which is more expandable.

[0046] In another embodiment, if Figure 1 As shown, the shape of the inner arch 12 is a truncated cone or a stepped cone.

[0047] The inner arch 12 has to withstand a relatively large water pressure inside the vacuum water storage tank 10 and the force brought by the water inlet pipe, so its shape is designed to be a truncated cone or a stepped cone, which improves its structural stability.

[0048] In another embodiment, if Figure 1 As shown, a sleeve 31 is disposed on the outer shell of the inner water inlet pipe 30 , and one end of the sleeve 31 is connected to a mounting plate 32 .

[0049] The provision of the sleeve 31 further improves the structural stability of the inner water inlet pipe 30 and can evenly transfer the force applied to the inner water inlet pipe 30 to the mounting plate 32 , thereby extending the service life of the inner water inlet pipe 30 and making it less prone to water leakage.

[0050] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
