Description

Technical Field

[0001] This utility model relates to the field of urban rainwater resource management and drainage technology, and in particular to a portable drainage outlet water flow detection device. Background Technology

[0002] In urban river management, the drainage outlets of retaining walls or drainage ditches are crucial components of the drainage system. Flow rate measurement is essential to quantify the amount of rainwater or sewage generated in the upstream catchment area and to provide data for research on rainwater or sewage pipe systems. Accurate flow rate measurement is necessary to ensure the accuracy of the research. However, existing methods for measuring flow rate have certain limitations.

[0003] Specifically, current drainage pipe and ditch systems also have some flow detection equipment, which generally uses ultrasonic waves to detect flow. In practical applications, users need to purchase and install existing flow detection equipment before data collection, resulting in lengthy preparation work and high procurement and maintenance costs. Furthermore, since a single flow detection system cannot cover all drainage outlets, a large number of devices are required if there are numerous outlets on a riverbank. Correspondingly, there is a lack of suitable equipment for manual data collection, leading to poor accuracy in flow detection data from drainage pipes or ditches requiring manual data collection. Utility Model Content

[0004] The purpose of this invention is to provide a portable drainage outlet water flow detection device that can detect the water flow at the drainage outlet in real time and directly collect the water flow to calculate the water flow rate.

[0005] This utility model is achieved through the following technical solution: a portable drain outlet water flow detection device, which includes a water collection bucket and a telescopic handle. The telescopic handle includes a handle rod arranged horizontally and a telescopic rod connected to the left and right ends of the handle rod and arranged vertically; the bottom ends of the two telescopic rods are respectively fixedly connected to the left and right ends of the water collection bucket.

[0006] The handle is equipped with a timer and a switch for controlling the timer;

[0007] The handle is also equipped with an auxiliary telescopic mechanism for driving the telescopic rod to extend and retract up and down.

[0008] Compared with previous technologies, the beneficial effects of this utility model are as follows:

[0009] 1. This utility model can conduct real-time on-site surveys and directly collect water from drainage outlets to calculate water flow, making water flow visible while also having the advantages of speed and convenience.

[0010] 2. The auxiliary telescopic mechanism is used to quickly control the up-and-down sliding and extension of the telescopic rod. Only a few staff members are needed to operate it to realize the statistics of water flow, saving manpower, material resources and financial resources. Attached Figure Description

Detailed Implementation

[0016] The present invention will now be described in detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description:

[0017] like Figures 1 to 4 As shown, a portable drain outlet water flow detection device includes a water collection tank 1 and a telescopic handle. The telescopic handle includes a handle rod 21 arranged horizontally and a telescopic rod 22 connected to the left and right ends of the handle rod 21 and arranged vertically. The bottom ends of the two telescopic rods 22 are fixedly connected to the left and right ends of the water collection tank 1, respectively.

[0018] The handle 21 is equipped with a timer 4 and a switch 5 for controlling the timer 4;

[0019] The handle 21 is also equipped with an auxiliary telescopic mechanism for driving the telescopic rod 22 to extend and retract vertically. This utility model can conduct real-time on-site surveys and directly collect water from the drain outlet to calculate water flow, making water flow visible while also offering the advantages of speed and convenience.

[0020] It should be noted that the timer 4 is a conventional technology. The timer 4 has a built-in display screen to show the time, as well as a battery and a battery charging port.

[0021] Furthermore, the auxiliary telescopic mechanism includes a roller 212 and a fixed pulley 213; the handle 21 has a cavity 211 inside, the roller 212 is rotatably connected to the middle of the cavity 211, and the fixed pulley 213 is rotatably connected to the left and right ends of the cavity 211;

[0022] The roller 212 has annular winding grooves 212-1 on the front and rear sides of its outer periphery. Each winding groove 212-1 is provided with a pulling rope 3. The top ends of the two pulling ropes 3 are fixedly connected to the upper and lower sides of the corresponding winding grooves 212-1, respectively. The two pulling ropes 3 pass around the corresponding fixed pulley 213 and extend downward to the end of the telescopic rod 22 and are tied to the rope hole provided on the water collection bucket 1.

[0023] The auxiliary telescopic mechanism also includes a rotating rod 214 and a limiting pin 216. The rotating rod 214 is rotatably connected to the outside of the handle rod 21. The bottom end of the rotating rod 214 is provided with a rotating shaft, which passes through the cavity 211 of the handle rod 21 and is fixedly connected to the roller 212.

[0024] The top surface of the handle 21 is provided with a connecting block 215. Two connecting blocks 215 are respectively located on the left and right sides of the rotating rod 214. The connecting blocks 215 are connected to the limiting pins 216 through connecting holes. The auxiliary telescopic mechanism is used to quickly control the up-and-down sliding and extension of the telescopic rod. Water flow can be counted with only a few operators, saving manpower, material resources, and financial resources. After the limiting pins 216 are connected, they limit the rotation of the rotating rod 214. After the telescopic rod is lowered to a suitable angle, the limiting pins 216 are connected to prevent the rotating rod 214 from continuing to rotate, thereby fixing the position of the water collection tank 1. At this time, the water flow from the drain outlet can be collected.

[0025] Furthermore, the telescopic rod 22 includes multiple telescopic unit tubes 221 sleeved together, with the diameter of the upper telescopic unit tube 221 being smaller than that of the lower telescopic unit tube 221.

[0026] Among them, the top end of the first telescopic unit tube 221 is fixedly connected to the bottom end of the handle 21, and the bottom end of the tail telescopic rod 22 is fixedly connected to the top end of the water collection tank 1.

[0027] Each pair of adjacent telescopic unit tubes 221 are slidably sleeved together and prevented from slipping by a limiting structure. The limiting structure includes a connecting flange 222 protruding outward from the bottom of the telescopic unit tube 221 and an inwardly contracting opening 223 at the top of the telescopic unit tube 221. The connecting flange 222 and the opening 223 cooperate to limit the movement. This structure of telescopic unit tubes 221 that are sleeved together and slidably connected allows the user to quickly lower the water collection bucket 1 to the drain outlet. After the water collection bucket 1 is collected, it can be quickly returned to the collection bucket 1 with the help of an auxiliary telescopic mechanism to calculate the water flow at the drain outlet as quickly as possible.

[0028] Furthermore, a plurality of threaded connectors 6 are fixedly connected to the bottom of the handle 21, and the threaded connectors 6 are threadedly connected to threaded support rods 61 extending in the front-rear direction through threaded holes. The threaded support rods 61 can cooperate with other auxiliary instruments to support the entire device.

[0029] Furthermore, the telescopic unit tube 221 is made of aluminum alloy, and the telescopic unit tube 221 is marked with graduations, with each section of the telescopic unit tube 221 being 40cm in length. This structure can help users quickly understand the approximate location of the drain outlet when they need to know its height.

[0030] Furthermore, the water collection tank 1 is a cuboid tank, and the dimensions of the water collection tank 1 are 400mm*250mm*350mm.

[0031] In summary, the method of using this utility model is as follows: Remove the limiting pin 216, and the user uses an auxiliary device to grasp the handle 21, then rotates the rotating rod 214 to allow the telescopic unit tube 221, which is fitted together with the telescopic rod 22, to gradually extend downwards until the water collection bucket 1 is lowered to the drain outlet or below the drain outlet. At this time, the auxiliary device is used to adjust the position of the entire utility model so that the water collection bucket 1 can collect water while simultaneously pressing the timer switch. After observing that the water collection bucket 1 is full of water, press the timer switch again. Then, rotate the rotating rod 214 in the opposite direction to slowly return the water collection bucket 1. The mass of the water in the water collection bucket 1 can then be observed, and the flow rate of the drain outlet can be calculated.

[0032] Although this utility model has been illustrated and described using specific embodiments and alternative methods, it should be understood that various changes and modifications are permitted as long as they do not depart from the spirit and scope of this utility model. Therefore, it should be understood that this utility model is not limited in any sense except by the appended claims and their equivalents.
