[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] The rainwater detection device for the rainwater well to be protected in the present application can be detachably installed in the rainwater well 201 to detect whether the rainwater inlet pipe 202 is discharging water into the rainwater well 201 .

[0035] like Figures 1 to 3 As shown, a rainwater detection device for a rainwater well provided in one embodiment of the present application includes a mounting bracket 10 , a bottom plate 20 , a discharge plate 30 and a water flow detection mechanism 40 .

[0036] In the present application, the base plate 20 can be installed at a position below the rainwater inlet pipe 202 through the installation bracket 10, and the drain plate 30 and the water flow detection mechanism 40 are both installed on the base plate 20, wherein a drain groove 31 is opened on the drain plate 30, and the drain plate 30 can receive water discharged from the rainwater inlet pipe 202, so that part of the water flows to the water flow detection mechanism 40 through the drain groove 31, and the remaining water flows out of the base plate 20 under the guidance of the drain plate 30; the water flow detection mechanism 40 can receive water passing through the drain groove 31 and generate a feedback signal. That is to say, when the rainwater detection device is working, the discharge plate 30 can divide the water introduced into the rainwater inlet pipe 202 into two parts. One part directly flows out of the bottom plate 20 under the guidance of the discharge plate 30, and the other part flows to the water flow detection mechanism 40 through the discharge groove 31 on the discharge plate 30, and then is detected by the water flow detection mechanism 40 and generates a feedback signal. The feedback signal generated when the water flow detection mechanism 40 is working is used to realize the judgment of whether the rainwater inlet pipe 202 is drained.

[0037] It can be understood that the rainwater detection device of the present application uses the discharge plate 30 to guide the water discharged from the rainwater inlet pipe 202 when working, and can directly discharge a large amount of impurities contained in the water from the bottom plate 20 under the guidance of the discharge plate 30, so as to ensure the detection of the water flow when the water flow detection mechanism 40 is working, and then has the function of protecting the water flow detection mechanism 40. It should be noted that the water flow to be detected when the water flow detection mechanism 40 is working can be specifically achieved by controlling the opening and position of the discharge groove 31 on the discharge plate 30, which will not be elaborated here.

[0038] In one embodiment, the mounting bracket 10 includes a main support rod 11, a first connecting rod 12, a second connecting rod 13, an adjusting rod 14 and an adjusting screw sleeve 15, the first connecting rod 12 and the second connecting rod 13 are both installed at one end of the main support rod 11. Specifically, the first connecting rod 12 and the second connecting rod 13 can be installed on the main support rod 11 at a 90° angle, wherein the first connecting rod 12 passes through the main support rod 11, and the base plate 20 is installed at the other end of the main support rod 11.

[0039] Among them, the adjusting rod 14 is connected to the second connecting rod 13 through the adjusting screw sleeve 15, and the adjusting screw sleeve 15 can adjust the distance between the adjusting rod 14 and the second connecting rod 13, so that when the mounting bracket 10 is installed on the rainwater well 201, the contact between the two ends of the first connecting rod 12 and an end of the adjusting rod 14 away from the second connecting rod 13 and the rainwater well 201 can be achieved, that is, three-point positioning is achieved. In this process, the distance between the adjusting rod 14 and the second connecting rod 13 can be adjusted by adjusting the screw sleeve 15 to achieve the adjustment of whether the adjusting rod 14 is in contact with the wall of the rainwater well 201, thereby realizing the disassembly and assembly between the adjusting rod 14 and the first connecting rod 12 and the rainwater well 201. It should be noted that the adjusting screw sleeve 15 and the second connecting rod 13 and the adjusting rod 14 can be connected by opposite threaded structures, so that when the adjusting screw sleeve 15 is rotated, the second connecting rod 13 and the adjusting rod 14 can be moved closer or farther away. Of course, in order to improve the stability of the installation of the mounting bracket 10 in the rainwater well 201, the ends of the first connecting rod 12 and the adjusting rod 14 for contacting the wall of the rainwater well 201 can be set to a pointed structure, which will not be elaborated here.

[0040] In one embodiment, the drain plate 30 includes a first guide plate portion 301 and a second guide plate portion 302, the first guide plate portion 301 and the second guide plate portion 302 are surrounded and form a cavity 300, and along the length direction of the bottom plate 20, the projection of the cavity 300 toward the water flow detection mechanism 40 can wrap the water flow detection mechanism 40. That is to say, the drain plate 30 of this embodiment is set as a bent plate structure, and ensures that the drain plate 30 diverts the water discharged from the rainwater inlet pipe 202 to avoid directly flushing the water flow detection mechanism 40, thereby protecting the water flow detection mechanism 40. It should be noted that the end of the first guide plate portion 301 and the end of the second guide plate portion 302 can be extended out of the bottom plate 20 to ensure that the drain plate 30 can divert the water discharged from the rainwater inlet pipe 202, and part of the water can pass through the drain groove 31 on the drain plate 30 and enter the position where the water flow detection mechanism 40 is located. Of course, the drain plate 30 is not limited to that shown in the figure. For those skilled in the art, the drain plate 30 can be set to other forms of structure.

[0041] The discharge groove 31 includes a first discharge groove portion 311 and a second discharge groove portion 312. The first discharge groove portion 311 is arranged between the first guide plate portion 301 and the bottom plate 20, and the second discharge groove portion 312 is arranged between the second guide plate portion 302 and the bottom plate 20, thereby specifically realizing an embodiment of the structural arrangement of the discharge groove 31 on the discharge plate 30.

[0042] In one embodiment, the bottom plate 20 is tilted downward relative to the rainwater inlet pipe 202 to ensure that the water introduced by the rainwater inlet pipe 202 can act on the discharge plate 30 and the water flow detection mechanism 40, thereby improving the working sensitivity of the rainwater detection device.

[0043] In one embodiment, the water flow detection mechanism 40 includes a terminal box 41, a signal detection component (not shown) and an impeller 42. The impeller 42 is rotatably mounted on the terminal box 41. The water passing through the discharge trough 31 can drive the impeller 42 to rotate relative to the terminal box 41. The rotating impeller 42 can cooperate with the signal detection component and generate a feedback signal, thereby specifically realizing the structure of the water flow detection mechanism 40. That is, when the water flow detection mechanism 40 is working, the water passing through the discharge trough 31 can flow to the impeller 42. Driven by the water flow, the impeller 42 can rotate on the terminal box 41, and the part of the impeller 42 whose shaft extends into the terminal box 41 can cooperate with the signal detection component and generate a feedback signal. It should be noted that a signal trigger may be provided on the rotating shaft of the impeller 42, and the signal detection component can cooperate with the signal trigger and generate a feedback signal. The signal trigger may be a ferromagnetic component fixed to the rotating shaft of the impeller 42, and the signal detection component may be a Hall sensor. The Hall sensor can detect the position of the ferromagnetic component to determine the rotation of the impeller 42, thereby achieving the purpose of detecting the water flow when the water flow detection mechanism 40 is working. Of course, the feedback signal generated by the signal detection component can be output outwardly using a wire and then sent to the terminal device wirelessly, and the terminal device can control the indicator light to emit different colors of light according to the feedback signal, which will not be elaborated here.

[0044] The impeller 42 is attached to the bottom plate 20 and is not in contact with the bottom plate 20 , so that the water passing through the drain groove 31 can stably drive the impeller 42 to rotate.

[0045] In one embodiment, the terminal box 41 is installed on the base plate 20 through the discharge plate 30 so that a preset gap is formed between the terminal box 41 and the base plate 20, thereby specifically realizing an embodiment of installing the terminal box 41 on the base plate 20, and the terminal box 41 is installed in the air so that the water introduced through the discharge groove 31 will not act on the terminal box 41, thereby preventing impurities contained in the water from accumulating at the position where the terminal box 41 is located and affecting the rotation of the impeller 42, thereby ensuring that the signal detection component in the terminal box 41 is driven by the impeller 42 to output an effective signal.

[0046] In another embodiment, a supporting foot 411 is installed on the terminal box 41 , and the terminal box 41 can be installed on the base plate 20 through the supporting foot 411 , thereby specifically realizing another embodiment of installing the terminal box 41 on the base plate 20 .

[0047] Furthermore, there are two impellers 42 , which are located on both sides of the terminal box 41 , so as to specifically implement the number setting of the impellers 42 , thereby improving the sensitivity of the water flow detection mechanism 40 to water flow detection when working.

[0048] In one embodiment, a sampling arc plate 50 is installed on the bottom plate 20. The sampling arc plate 50 is arranged on the side of the water flow detection mechanism 40 away from the discharge plate 30, and the sampling arc plate 50 can cooperate with the bottom plate 20 to partially intercept the water passing through the water flow detection mechanism 40, so that the rainwater detection device can also sample the water discharged from the rainwater inlet pipe 202 when working, which further facilitates the water quality judgment of the water discharged from the rainwater inlet pipe 202.

[0049] In summary, the rainwater detection device for the rainwater well of the present application has a simple overall structure, which is convenient for operators to carry out replacement, maintenance and detection outside the rainwater well. When the rainwater detection device is working, it can determine whether the rainwater inlet pipe 202 is draining water for detection, and then combine it with whether it is raining at the time to determine whether the rainwater inlet pipe 202 in the rainwater well 201 is secretly connected to a sewage pipe.

[0050] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
