Description

Technical Field

[0001] This utility model relates to the field of urban flooding monitoring and sensing technology, and in particular to a device and system for monitoring water accumulation on urban roads. Background Technology

[0002] In recent years, with global climate change and my country's rapid urbanization, urban flooding caused by heavy rainfall has become a frequent problem. Urban flooding not only causes traffic congestion and affects citizens' travel, but in severe cases, it can also lead to major casualties and property losses. Therefore, it is very important to detect urban flooding incidents in a timely manner and respond quickly to the scene.

[0003] Currently, non-contact and contact monitoring devices such as radar level gauges, pressure level gauges, and electronic water tanks are widely used to detect urban flooding events. These monitoring devices can monitor road water levels in real time, but they also have the following problems:

[0004] 1. Its large size obstructs the passage of vehicles and pedestrians;

[0005] 2. The equipment requires a large amount of daily maintenance and has high purchase costs;

[0006] 3. Radar level gauges are also affected by passing vehicles, which can easily cause false alarms and other problems. Utility Model Content

[0007] The purpose of this invention is to overcome the technical problems existing in the current monitoring equipment and to provide a monitoring device and system for urban road water accumulation.

[0008] The objective of this utility model is achieved through the following technical solution:

[0009] In a first aspect, a device for monitoring urban road waterlogging is provided, comprising a housing, which is vertically installed on the side of a curb and has a top cover connected thereto. The housing contains a first cavity and a second cavity. The first cavity contains a battery and a remote terminal unit. The second cavity contains at least two sets of electrode sensors arranged vertically. Waterproof wires are used to connect the battery, the remote terminal unit, and the electrode sensors respectively. The waterproof wires pass through the second cavity from the first cavity through a waterproof connector. A water inlet is provided at the bottom of the second cavity.

[0010] In some embodiments, the housing and the top cover are connected by screws, and a potting sealing ring is provided at the contact edge of the two.

[0011] In some embodiments, the electrode sensor consists of two stainless steel metal sheets, which are fixed to the electrode sensor bracket with glass glue; the electrode sensor bracket is detachably installed in the fixing hole in the second cavity by bracket fixing screws.

[0012] In some embodiments, the waterproof wire and electrode sensor are welded together.

[0013] In some embodiments, the side of the second cavity is provided with a plurality of water inlets.

[0014] In some embodiments, a filter screen is provided in the water inlet.

[0015] In a second aspect, an urban road waterlogging monitoring system is provided, including the monitoring device described in the first aspect, and also including an intelligent sensing platform, wherein the intelligent sensing platform is connected to the remote terminal unit via a wireless network.

[0016] It should be further noted that the technical features corresponding to the above embodiments can be combined or substituted with each other to form new technical solutions without conflict.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The housing of this utility model is provided with a first cavity and a second cavity, which respectively accommodate the battery, the remote terminal unit and the electrode sensor. By rationally partitioning, redundant space is reduced and a high degree of integration is achieved. The housing is vertically installed on the side of the curb, and the overall size is adapted to the side of the curb of urban roads. After installation, it does not exceed the range of the curb and avoids interference with the passage of vehicles and pedestrians.

[0019] 2. This utility model device uses an electrode sensor composed of stainless steel metal sheets as a water accumulation sensing and monitoring device, which is low in cost; at the same time, the number of electrode sensors can be increased or decreased according to the actual situation of the waterlogging point and the actual needs of triggering alarms, and the vertical height position of the electrode sensor can be flexibly adjusted by screws, so that the water level threshold can be adjusted without additional expansion of the cavity volume.

[0020] 3. The outer cover of this utility model device is tightly connected to the housing by screws. Combined with the potting seal ring and IP68 waterproof rating, it can meet the waterproof requirements without the need for an external large protective structure, thus achieving a miniaturized waterproof function.

[0021] 4. The bottom and side surfaces of the cavity containing the electrode sensor of this utility model are provided with water inlets. When road water accumulates to a certain height, it flows into the cavity through the water inlets, preventing false alarms caused by water trucks or rain spray. At the same time, multiple water inlets serve to drain accumulated water and dissipate moisture, preventing false alarms caused by high moisture content in the cavity. In addition, the water inlets are equipped with filters to prevent impurities in the road water from entering the housing, avoiding frequent equipment maintenance, reducing the maintenance workload of the monitoring equipment, and preventing impurities from adhering to the sensor and causing false alarms.

[0031] Reference Figures 1-3 In one exemplary embodiment, an urban road waterlogging monitoring device is provided, including a housing 3, which is vertically installed on the side of a curb and has a top cover 1 connected to it. The housing 3 has a first cavity 4 and a second cavity 5. The first cavity 4 is provided with a battery 7 and a remote terminal unit (RTU). The second cavity 5 is provided with at least two sets of electrode sensors 11 arranged vertically. A waterproof wire 9 is used to connect the battery 7, the remote terminal unit 8 and the electrode sensors 11 respectively. The waterproof wire 9 passes through the second cavity 5 from the first cavity 4 through a waterproof connector 10. A water inlet 14 is provided at the bottom of the second cavity 5.

[0032] Preferably, the housing 3 and the upper cover 1 are connected by screws. Specifically, the housing 3 and the upper cover 1 are connected by housing fixing screws to form the outer shell of the device. At the same time, a potting sealing ring 2 is provided at the contact edge between the housing 3 and the upper cover 1. After the upper cover 1 and the housing 3 are connected, the first cavity 4 adopts an IP68 waterproof design. The outer cover 1 and the housing 3 are tightly connected by screws. Combined with the potting sealing ring 2 and the IP68 waterproof rating, the waterproof requirements can be met without the need for a large external protective structure, realizing a miniaturized waterproof function.

[0033] The electrode sensor 11 consists of two stainless steel metal sheets, which are fixed to the electrode sensor bracket 15 with glass glue.

[0034] Furthermore, the waterproof wire 9 and the electrode sensor 11 are welded together.

[0035] Preferably, the second cavity 5 is provided with multiple water inlets 14 on its side. This means that water inlets 14 are provided on both the bottom and side surfaces of the cavity where the electrode sensor 11 is located. When road water accumulates to a certain height, it flows into the second cavity 5 through the water inlets 14, preventing false alarms caused by water trucks or rain spray. At the same time, the multiple water inlets 14 also serve to drain accumulated water and dissipate moisture, preventing false alarms caused by high moisture content in the cavity.

[0036] Furthermore, a filter screen is provided in the water inlet 14 to prevent impurities in the road water from entering the housing 3, avoid frequent equipment maintenance, reduce the maintenance workload of the monitoring equipment, and prevent impurities from adhering to the electrode sensor 11 and causing false alarms.

[0037] In summary, this utility model significantly reduces the overall size of the device and achieves the goal of miniaturization by optimizing the cavity layout, adapting to the size of the curbstone, using modular components, and employing a highly integrated waterproof design.

The intelligent sensing platform then issues an alarm and notifies relevant personnel to handle the situation via SMS and telephone.

[0039] The above detailed embodiments are a detailed description of the present utility model. It should not be considered that the specific embodiments of the present utility model are limited to these descriptions. For those skilled in the art, several simple deductions and substitutions can be made without departing from the concept of the present utility model, and all of these should be considered to fall within the protection scope of the present utility model.
