AI Technical Summary
The existing water regulating and storage tank overflow pipes cannot effectively prevent small insects and sand and dust from entering the water tank from being smaller than the diameter of the screen hole. At the same time, these measures will lead to a reduction in the effective water overflow area of the overflow pipe and reduce the overflow drainage.
A overflow flare device is designed using the floating ball to automatically open and close. The floating ball automatically opens and closes the water outlet at the bottom of the overflow flare by buoyancy. When there is no water in the overflow flare, the floating ball covers the water outlet to isolate the entry of organisms and dust; when the overflow flare inlet, the water buoyancy lifts the floating ball, and the overflow water can be discharged smoothly.
It effectively prevents insects and dust from entering the water tank, and does not affect the overwater area and drainage of the overflow pipe, solving the problems of the reduction of overflow pipe overwater area and drainage of the overflow pipe caused by traditional protective measures.

Description
Technical Field
[0001] The utility model relates to the technical field of secondary pressurization and storage water supply for buildings and communities, and specifically relates to an insect-proof and dust-proof device for an overflow pipe of a storage water tank. Background Technique
[0002] The development of the secondary water supply technology in China has successively gone through stages such as water tower / high-level water tank water supply, pump-water tank combined water supply, pneumatic water supply, variable frequency speed regulation water supply, network superimposed pressure water supply, digital integrated full variable frequency constant pressure water supply, etc. Except for a few projects that can adopt network superimposed pressure water supply without being restricted by the urban pipe network diameter and water supply pressure, most secondary water supply systems need to set up storage water tanks (pools), and all involve the problems of the stability and maintenance of the water quality in the water tanks (pools).
[0003] On the one hand, the water supply quality of the water tank (pool) depends on the safety protection measures of the overflow pipe and the vent pipe connected to the external space air, and on the other hand, it depends on the water age and disinfection facilities. The diameter of the overflow pipe of the water tank (pool) is generally 2-3 sizes larger than that of the vent pipe and its water outlet is close to the ground. The risk of entering organisms and dust is much greater than that of the vent pipe, and it has become the weakest link in maintaining the water quality of the water tank (pool).
[0004] The existing technology has the following problems: Currently, the existing overflow pipes of storage water tanks usually set up protective nets or dirt removers at the end of the overflow pipe, and the essence of the protective net and the dirt remover is basically the same, both of which use filter screens for protection and dirt removal. However, setting up a protective net can only prevent insects larger than the sieve hole diameter from entering the water tank, but it is powerless against small insects and dust smaller than the sieve hole diameter; the water flow in the overflow pipe is gravity flow, and its flow rate completely depends on the size of the flow cross-section. When using a protective net, it will inevitably cause a reduction in the effective water passing area of the pipeline. Taking a 30-mesh filter screen as an example, its actual water passing area is about half of the inner diameter of the pipe. Content of the Utility Model
[0005] Aiming at the deficiencies of the existing technology, the utility model provides an insect-proof and dust-proof device for an overflow pipe of a storage water tank, which solves the problems of sacrificing the effective water passing area of the overflow pipe and reducing the overflow drainage volume in the existing protective net and the filter screen filtering method of the dirt remover while achieving the goal of effective insect prevention and dust prevention.
[0006] To achieve the above purpose, the utility model provides the following technical solution: An insect-proof and dust-proof device for an overflow pipe of a storage water tank, including a water tank, the water tank is provided with an overflow pipe, one end of the overflow pipe is provided with an overflow bell mouth inside the water tank, a bracket is arranged between the upper end of the overflow pipe and the inner wall of the water tank, and the lower end of the overflow bell mouth is provided with a bell mouth water outlet;
[0007] A floating ball is arranged inside the overflow bell mouth, a fixed blocking facility is arranged above the overflow bell mouth, or a movable blocking facility is arranged above the overflow bell mouth, and a wing plate is arranged on the upper edge of the overflow bell mouth;
[0008] The fixed blocking facility includes a gasket and fixed grid bars. The fixed grid bars are fixedly installed on the upper surface of the gasket. The fixed blocking facility is used to prevent the floating ball from escaping from the range of the overflow bell mouth;
[0009] The outer diameter of the floating ball should be 1 - 2 sizes larger than the inner diameter of the water outlet of the bell mouth.
[0010] As a preferred technical solution of the present utility model, the movable blocking facility includes a base, vertical grid bars, a top ring, horizontal grid bars and a blocking block. The vertical grid bars are fixedly installed above the base, the horizontal grid bars are fixedly installed inside the top ring, and the blocking block is located outside the base.
[0011] As a preferred technical solution of the present utility model, one end of the bracket is fixedly installed on the inner wall of the water tank, the other end of the bracket is fixedly installed with the upper end of the overflow pipe, the bottom of the overflow bell mouth is welded with the same diameter as the overflow pipe, and the floating ball is made of stainless steel / copper material, and the surface of the ball is smooth.
[0012] As a preferred technical solution of the present utility model, the wing plate is annular, the wing plate is fixedly installed on the outer edge of the top of the overflow bell mouth or integrally cast with the overflow bell mouth, the floating ball is located within the space enclosed by the overflow bell mouth and the fixed blocking facility or the movable blocking facility, and the fixed blocking facility is made of the same material as the overflow pipe.
[0013] As a preferred technical solution of the present utility model, the gasket is made of metal material, the gasket is connected to the wing plate by welding, and the gasket is connected to the fixed grid bars by welding.
[0014] As a preferred technical solution of the present utility model, both the gasket and the fixed grid bars are provided with eight groups, and are arranged equidistantly and circumferentially above the wing plate. The clear distance between the fixed grid bars is smaller than the outer diameter of the floating ball.
[0015] As a preferred technical solution of the present utility model, the base is annular, eight groups of vertical grid bars are arranged equidistantly and circumferentially above the base, the vertical grid bars are connected to the base by welding, the horizontal grid bars are connected to the top ring by welding, the blocking block is provided with four groups, and is arranged circumferentially on the upper surface of the wing plate. The blocking block is welded on the surface of the wing plate, and the movable blocking facility is made of the same material as the overflow pipe.
[0016] Compared with the prior art, the present utility model provides a device for preventing insects and dust in the overflow pipe of a regulating water tank, and has the following beneficial effects:
[0017] The insect and dust prevention device for the overflow pipe of the storage water tank uses the buoyancy of a floating ball to automatically open and close the water outlet at the bottom of the overflow bell mouth. When there is no water in the overflow bell mouth, the floating ball covers the water outlet at the bottom of the overflow bell mouth by its own weight, which can isolate organisms and dust from entering the water tank. When the overflow bell mouth is filled with water, the buoyancy of the water lifts the floating ball, and the overflow water enters the overflow pipe from the water outlet at the bottom of the overflow bell mouth and is discharged from the water tank. Therefore, this device solves the disadvantages of traditional mesh insect prevention measures such as setting a filter screen at the end of the overflow pipe outlet, which cannot prevent small insects and dust, and does not sacrifice the cross-sectional area of the overflow pipe for water flow, having no impact on the overflow drainage volume.

[0026] Please refer to Figure 1-6 , in this implementation: An anti-insect and dust-proof device for the overflow pipe of a storage water tank, comprising a water tank 1, an overflow pipe 2 is arranged inside the water tank 1, one end of the overflow pipe 2 is provided with an overflow bell mouth 3, a bracket 7 is arranged outside the overflow pipe 2, and a bell mouth water outlet 8 is arranged below the overflow bell mouth 3;
[0027] A floating ball 4 is arranged inside the overflow bell mouth 3, a fixed blocking facility 5 is arranged above the overflow bell mouth 3, and a movable blocking facility 6 is arranged above the overflow bell mouth 3. A wing plate 9 is arranged on the upper edge of the overflow bell mouth 3;
[0028] The fixed blocking facility 5 includes a gasket 51 and fixed grid bars 52. The fixed grid bars 52 are fixedly installed on the upper surface of the gasket 51. The fixed blocking facility 5 is used to prevent the floating ball 4 from escaping from the range of the overflow bell mouth 3;
[0029] The outer diameter of the floating ball 4 should be 1 - 2 sizes larger than the inner diameter of the bell mouth water outlet 8.
[0030] Please refer to Figure 2 , Figure 5 and Figure 6 , in this embodiment, the movable blocking facility 6 includes a base 61, vertical grid bars 62, a top ring 63, horizontal grid bars 64 and a stop block 65. The vertical grid bars 62 are fixedly installed above the base 61, the horizontal grid bars 64 are fixedly installed inside the top ring 63, and the stop block 65 is located outside the base 61.
[0031] In the above embodiment, the vertical grid bars 62 can be installed and fixed under the action of the top ring 63 and the base 61. At the same time, since the top ring 63 is a ring structure, the horizontal grid bars 64 can be installed and fixed through the top ring 63;
[0032] Specifically, the base 61 is a ring. Eight groups of vertical grid bars 62 are arranged equidistantly and circumferentially above the base 61. The vertical grid bars 62 are connected to the base 61 by welding. The horizontal grid bars 64 are connected to the top ring 63 by welding. Four groups of stop blocks 65 are arranged and circumferentially distributed on the upper surface of the wing plate 9. The stop blocks 65 are welded to the surface of the wing plate 9. The movable blocking facility 6 is made of the same material as the overflow pipe 2;
[0033] With the cooperation of eight groups of vertically arranged vertical bars 62 and horizontal bars 64 at equal intervals, the floating ball 4 is prevented from escaping from the overflow bell mouth 3. The vertical bars 62, the base 61, the top ring 63 and the horizontal bars 64 are integrally formed by welding. At the same time, the stop block 65 is welded on the wing plate 9 to limit the above-mentioned whole, so that the movable blocking facility 6 can be disassembled and assembled conveniently; in order to prevent the floating ball 4 from escaping from the range of the overflow bell mouth 3, the net distance of the gaps between the horizontal bars 64 and the vertical bars 62 should be smaller than the outer diameter of the floating ball 4.
[0034] Please refer to Figure 1 、 Figure 2 and Figure 3 , in this embodiment, the wing plate 9 is annular, the wing plate 9 is fixedly installed on the outer edge of the top of the overflow bell mouth 3 and integrally cast with the overflow bell mouth 3. The floating ball 4 is located within the space enclosed by the overflow bell mouth 3, the fixed blocking facility 5 and the movable blocking facility 6. The fixed blocking facility 5 is made of the same material as the overflow pipe 2.
[0035] In the above embodiment, the fixed blocking facility 5 and the movable blocking facility 6 can be installed under the action of the wing plate 9 installed on the upper edge of the overflow bell mouth 3. In the specific use process, one of the two blocking facilities can be selected for use, so as to realize the blocking of the floating ball 4 inside the overflow bell mouth 3 to prevent it from jumping out of the overflow bell mouth 3.
[0036] Furthermore, one end of the bracket 7 is fixedly installed on the inner wall of the water tank 1, the other end of the bracket 7 is fixedly installed with the upper end of the overflow pipe 2, the bottom of the overflow bell mouth 3 is welded with the overflow pipe 2 of the same diameter, and the floating ball 4 is made of stainless steel and all-copper materials, and the surface of the sphere is smooth.
[0037] Under the action of the bracket 7, the overflow pipe 2 can be fixedly installed inside the water tank 1. At the same time, the welding of the overflow bell mouth 3 and the overflow pipe 2 enables the liquid inside the overflow bell mouth 3 to enter the overflow pipe 2 through the bell mouth outlet 8 and be discharged from the water tank 1.
[0038] Please refer to Figure 1 、 Figure 3 and Figure 4 , in this embodiment, the gasket 51 is made of metal, the gasket 51 is connected to the wing plate 9 by welding, and the gasket 51 is connected to the fixed bar 52 by welding.
[0039] In the above embodiment, the gasket 51 made of metal can be welded and fixed in cooperation with the wing plate 9. Since the fixed bar 52 is also made of metal, the gasket 51 can be welded and fixed to the fixed bar 52.
[0040] Among them, it is worth noting that there are eight groups of both the gasket 51 and the fixed grid bars 52, and they are arranged equidistantly and circumferentially around the upper part of the wing plate 9. The clear distance between the fixed grid bars 52 is smaller than the outer diameter of the floating ball 4.
[0041] Due to the equidistant arrangement of the gasket 51 and the fixed grid bars 52, and the clear distance between the fixed grid bars 52 being smaller than the outer diameter of the floating ball 4, the fixed grid bars 52 can block the floating ball 4 in the overflow bell mouth 3 to prevent it from jumping out of the overflow bell mouth 3.
[0042] The working principle and usage process of the present utility model: When there is no water in the overflow bell mouth 3, the floating ball 4 covers the bell mouth water outlet 8 at the bottom of the overflow bell mouth 3 by its own weight, isolating organisms and dust from entering the water tank 1; when the water level in the overflow bell mouth 3 reaches a certain depth, the buoyancy of the water lifts the floating ball 4, and the overflow water enters the overflow pipe 2 from the bell mouth water outlet 8 at the bottom of the overflow bell mouth 3 and is discharged from the water tank 1; under the action of the floating ball 4 fixing and blocking facility 5 or the movable blocking facility 6 arranged along the horizontal wing plate 9 of the overflow bell mouth 3, it can prevent the floating ball 4 from jumping out of the range of the overflow bell mouth 3 during the overflow drainage.
