Description

Technical Field

[0002] As an important part of urban infrastructure, drainage pipes bear the important task of discharging rainwater and sewage. However, with the acceleration of urbanization, the drainage pipe system faces increasingly complex challenges, such as frequent problems such as pipe aging, blockage, and leakage, which bring many inconveniences to urban operations and residents' lives. Therefore, it is particularly important to conduct regular and accurate liquid level detection on drainage pipes. Traditional drainage pipe level detection methods, such as manual observation and float-type liquid level gauges, have many shortcomings. Manual observation methods are inefficient and easily affected by human factors, while float-type liquid level gauges may cause inaccurate measurements due to factors such as dirt and corrosion in the pipe. In addition, these methods are often unable to adapt to pipes of different shapes and sizes, as well as complex and changing working environments. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] As a preferred embodiment of the utility model of a device for detecting the liquid level of an underground drainage pipeline in an inspection well, Figure 1-Figure 3As shown, this embodiment provides a device for detecting the liquid level of an underground drainage pipe in an inspection well, comprising a telescopic tube 1, wherein the outside of the telescopic tube 1 is provided with a scale, and the scale of the telescopic tube 1 is continuous in the extended state, the top of the telescopic tube 1 is connected to a laser rangefinder 2, and the outer wall of the end of the telescopic tube 1 is also connected to a power supply 3, and the power supply 3 is used to power the laser rangefinder 2, an isolation net 4 is arranged at the lower end of the telescopic tube 1, and a buoy 5 is placed on the isolation net 4, the laser rangefinder 2 is used to vertically emit a laser toward the inside of the telescopic tube 1 and measure the distance between the laser rangefinder 2 and the buoy 5, and the telescopic tube 1 is connected to an L-shaped steering tube 6 at the lower end of the isolation net 4, and 2-4 water inlet holes 7 are opened on the tube wall of the L-shaped steering tube 6; the telescopic tube 1 is made of stainless steel.

[0021] In the principle of the utility model, the laser rangefinder 2 is the core component, which uses a laser beam for non-contact measurement. The laser rangefinder emits a laser beam to the reflective surface on the buoy, and then receives the reflected laser. By measuring the time difference from laser emission to reception, combined with the known value of the speed of light, the distance from the laser rangefinder to the buoy can be accurately calculated. Since the laser has the characteristics of good directionality and strong anti-interference ability, the laser rangefinder can provide very accurate measurement data.

[0022] The implementation principle of the above embodiment is as follows. In actual use, for example, when measuring the water depth of the drainage pipe in the inspection well, since the depth of the inspection well can reach 3-5 meters or even higher, manual measurement is very dangerous, and there is currently no accurate measurement method. With the utility model, the operator first extends the telescopic tube 1 into the inspection well, extends the L-shaped steering tube 6 to the bottom of the drainage pipe, and adjusts the length of the telescopic tube 1. Then, turn on the laser rangefinder 2, observe and record the distance data displayed by the laser rangefinder 2. At this time, the distance data measured is actually the distance from the laser rangefinder 2 to the buoy 5. Since the length of the telescopic tube 1 can be directly read according to the scale, it can be obtained through simple mathematical calculations, such as Figure 3 As shown, the water depth data is obtained through Hh. That is, the liquid level height data is obtained.

[0023] At the same time, the design of the L-shaped steering tube 6 in the above embodiment enables the utility model to extend deeper into the drainage pipe, and is particularly suitable for pipes that are curved or difficult to directly observe. The L-shaped steering tube 6 can be selected to be a right angle, and the right angle structure enables it to extend deep into the pipe by turning when the telescopic rod cannot be directly extended. This design enables the laser rangefinder 2 to perform accurate measurements no matter where the buoy 5 is in the pipe.

[0024] In some preferred embodiments, Figure 1As shown, a microprocessor 8 is also connected to the outer wall of the end of the telescopic tube 1, and the microprocessor 8 is electrically connected to the power supply 3 and the laser rangefinder 2. The microprocessor 8 processes the signal received by the laser rangefinder 2 and calculates the distance. The microprocessor 8 with an automatic calibration function can be selected to eliminate the influence of environmental factors (such as temperature, humidity, etc.) on the measurement results.

[0025] In some preferred embodiments, in order to improve the accuracy of detection and prevent the buoy 5 from getting stuck, in this embodiment, the diameter of the buoy 5 is smaller than the minimum diameter of the telescopic tube 1 .

[0026] In some preferred embodiments, Figure 2 As shown, the water inlet hole 7 is provided at the bottom of the L-shaped steering tube 6, so that when in use, the water inlet direction is perpendicular to the water flow direction, and at the same time, due to the blocking effect of the tube body, static pressure can be formed in the tube, thereby preventing the water flow in the drainage pipe from causing fluctuations in the water level and affecting the accurate positioning of the buoy 5, thereby causing errors in the calculation results.

[0027] Finally, 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 purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
