Description

Technical Field

[0001] The utility model relates to the technical field of rainwater utilization, in particular to a uniform flow abandonment device for a rainwater flower box. Background Art

[0002] As a relatively abundant water resource, rainwater resource utilization has become an effective way to solve the shortage of water resources. Rainwater collection and utilization mainly involves storing the collected rainwater in reservoirs, and then using it for landscape flower boxes, spraying roads, greening irrigation, etc. after proper treatment. In the process of rainwater collection, due to the high pollutant content in the initial rainwater, and then as the runoff continues, the pollutant content will gradually decrease and tend to stabilize. Therefore, in the process of rainwater collection for flower box water replenishment, it is necessary to use the uniform flow discharge device of the rainwater flower box to complete the discharge of the initially collected rainwater.

[0003] At present, the uniform flow abandonment devices of rainwater flower boxes used in the field of rainwater utilization generally adopt analytical or electronic abandonment devices. Among them, the abandonment flow rate of mechanical uniform flow abandonment devices is often fixed at the factory and cannot be adjusted later. In actual applications, the air pollution conditions in different regions or the pollution conditions in different climates in the same region often have obvious differences. The uniform flow abandonment device with a fixed abandonment flow rate cannot adjust the abandonment flow rate according to the air pollution conditions, which may easily lead to high pollution or dust in the collected rainwater, which cannot meet the water demand of the flower box.

Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In view of the problems existing in the above-mentioned conventional uniform flow abandonment device of the rainwater flower box, the present utility model is proposed.

[0006] Therefore, the purpose of the utility model is to provide a uniform flow abandonment device for a rainwater flower box, which is suitable for solving the problem that a uniform flow abandonment device with a fixed abandonment flow rate cannot adjust the abandonment flow rate according to the air pollution conditions, which easily leads to a high degree of pollution or dust in the collected rainwater and fails to meet the water demand of the flower box.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a uniform flow abandonment device for a rainwater flower box, comprising:

[0025] Example

[0026] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides a uniform flow abandonment device for a rainwater flower box, including: a uniform flow abandonment unit 100 and a flow abandonment adjustment unit 200.

[0027] The uniform flow abandonment unit 100 includes a flower box top plate 101 and a flow abandonment box 102 located above the flower box top plate 101. A scale window 106 is inlaid on the side wall of the flow abandonment box 102. The scale window 106 is provided with evenly distributed scale lines. The scale window 106 is provided without opening the flow abandonment box 102. The staff can directly observe the amount of rainwater stored in the flow abandonment box 102. The top of the flow abandonment box 102 is fixedly connected to multiple groups of evenly distributed water inlet covers 103. The water inlet covers 103 are set to be trumpet-shaped with a large opening at the upper end and a small opening at the lower end. This arrangement increases the amount of rainwater received by the water inlet cover 103 per unit time, and the lower end of the side wall of the flow abandonment box 102 is fixedly connected to multiple groups of evenly distributed water inlet covers 103. The abandoned flow pipes 104 are evenly distributed, and a matching electric control valve 105 is fixedly installed on each abandoned flow pipe 104. A plurality of evenly distributed telescopic columns 108 are fixedly connected between the lower side wall of the abandoned flow box 102 and the upper side wall of the flower box top plate 101. A corresponding return spring 109 is sleeved on each telescopic column 108. A power supply 107 is fixedly installed on the upper side wall of the flower box top plate 101. The power supply 107 is located below the abandoned flow box 102. A waterproof cover is fixedly sleeved on the outer side of the power supply 107, and a layer of anti-corrosion coating with uniform thickness is plated on the surface of the waterproof cover. The setting of the waterproof cover effectively solves the defect that rainwater easily wets the power supply 107, and the setting of the anti-corrosion coating improves the anti-corrosion ability of the waterproof cover;

[0028] Secondly, the abandoned flow regulating unit 200 includes a threaded rod 201 rotatably installed on the upper side wall of the flower box top plate 101 and a lifting block 202 threadedly connected to the threaded rod 201, a symmetrical guide rod 203 is fixedly installed on the flower box top plate 101, and a guide sleeve 204 is vertically slidably connected to the guide rod 203, each guide sleeve 204 is fixedly connected to the lifting block 202, an elastic extrusion switch 205 electrically connected to the electric control valve 105 is fixedly installed on the side wall of the lifting block 202, and the elastic extrusion switch 205 and the electric control valve 105 are both electrically connected to the power supply 107, a connecting block 206 is fixedly installed on the lower side wall of the abandoned flow box 102, and an extrusion block 207 symmetrically positioned to the elastic extrusion switch 205 is fixedly installed on the lower end of the side wall of the connecting block 206.

[0029] Furthermore, the uniform flow abandonment unit 100 also includes a water inlet dust prevention component 110, which includes an annular plugging plate 110a fixedly mounted on the lower end of the inner wall of the water inlet cover 103, a water outlet is provided at the center of the annular plugging plate 110a, and a matching float 110b is provided in the water outlet, the lower side wall of the annular plugging plate 110a is connected to the float 110b by a connecting rope 110c, and the connecting rope 110c runs through the water outlet, and a plurality of groups of evenly distributed overflow holes are provided on the upper end of the side wall of the abandonment box 102, the float 110b is provided in a hollow structure, and the connecting rope 110c is woven from an elastic material; through the float 110b and the annular plugging plate 1 By using 10a and the connecting rope 110c, when rainwater enters the water inlet cover 103 and gradually accumulates, the buoyancy of the float 110b gradually increases, and the float 110b rises and the water outlet opens. When the water in the waste flow box 102 is full, the rainwater entering the waste flow box 102 is discharged through the overflow hole. Because the drainage rate of the overflow hole is greater than the water receiving rate of the water inlet cover 103, the water volume in the water inlet cover 103 gradually decreases, and the float 110b is blocked by gravity to complete the collection of rainwater during rainfall, and the water outlet can be closed after the collection is full, so as to prevent external dust from passing through the water outlet to pollute the water source in the waste flow box 102.

[0030] During use, when the air pollution condition worsens, the threaded rod 201 is rotated forward, and the lifting block 202 threadedly connected to the threaded rod 201 moves downward under the guidance of the guide rod 203 and the guide sleeve 204. Under the condition of constant rain, the time for the squeezing block 207 to trigger the elastic squeezing switch 205 is extended, thereby increasing the initial rainwater discharge flow rate and ensuring that the pollution degree of the subsequent collected rainwater is small and constant. On the contrary, when the air pollution condition is alleviated, the threaded rod 201 is rotated reversely, and the lifting block 202 drives the elastic squeezing switch 205 to rise, shortening the time for the squeezing block 207 to trigger the elastic squeezing switch 205, thereby reducing the initial rainwater discharge flow rate. The rainwater discharge flow rate of the uniform flow discharge device can be flexibly adjusted according to the air pollution condition to meet the water demand of the flower box.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
