Abstract
Description
Technical Field
[0001] This utility model relates to the field of water level monitoring equipment, and in particular to an underground water accumulation monitoring device for urban flooding. Background Technology
[0002] To minimize the losses caused by urban flooding, it is necessary to strengthen the construction of urban drainage infrastructure and to fully grasp the real-time situation of urban flooding, and to monitor the water levels in urban culverts, low-lying road sections, and other areas in real time.
[0003] A Chinese patent, CN219776841U, discloses an intelligent waterlogging monitoring device for urban flooding, comprising a riser and a drive unit. The riser has a support shaft rotatably connected to its upper end via a bearing. A crossbar is located at the upper end of the support shaft, and a protective shell is located at the left end of the crossbar. A radar level gauge is located at the lower end inside the protective shell. A protective box is located in the middle of the outer arc surface of the riser, and a data transmitter is located at the upper end of the rear side wall of the protective box. The drive unit is located at the upper end of the riser, and its upper end is fixedly connected to the lower surface of the crossbar. The device also includes a controller, located at the lower end of the rear side wall of the protective box. The output end of the radar level gauge is electrically connected to the input end of the controller. This intelligent waterlogging monitoring device for urban flooding allows the crossbar fixing the radar level gauge to rotate, thereby increasing the detection range of the radar level gauge, ensuring detection accuracy, and facilitating the maintenance of the radar level gauge.
[0004] The monitoring equipment in the aforementioned patent still has certain shortcomings. Since most existing underground water accumulation monitoring equipment is buried underground through straight pipes and is fixed, when there is too much underground water surging up, the fixed monitoring equipment is easily submerged and damaged, losing its basic monitoring function. Utility Model Content
[0005] This utility model provides an underground waterlogging monitoring device for urban areas, which solves the problem that existing monitoring devices are easily submerged by water.
[0006] This utility model provides an underground water accumulation monitoring device for urban flooding, including an installation cylinder, a monitoring cavity inside the installation cylinder, a water inlet hole communicating with the monitoring cavity at the bottom of the installation cylinder, and a balance hole communicating with the monitoring cavity at the top of the installation cylinder. A water level sensor is installed inside the monitoring cavity to monitor the height of the water level entering the monitoring cavity; A foam buoyancy plate is fixedly connected to the top of the water level sensor. The foam buoyancy plate raises the height of the water level sensor as the water level in the monitoring chamber rises, so as to keep the top of the water level sensor above the water surface.
[0007] Furthermore, the mounting cylinder includes a cylinder body, a top connecting seat, a top cover plate, and a battery pack. The monitoring chamber is disposed within the cylinder body. The top connecting seat is fixedly connected to the top of the cylinder body. An installation compartment is provided on the top connecting seat. The battery pack is disposed within the installation compartment. The top cover plate is detachably connected to the top connecting seat and covers the installation compartment. The battery pack is connected to the water level sensor via a wire, and the battery pack is used to power the water level sensor.
[0008] Furthermore, the foam buoyancy disk is configured as a ring structure, and the end of the water level sensor passes through the middle of the foam buoyancy disk.
[0009] Furthermore, a support connecting rod is fixedly connected inside the monitoring cavity. The support connecting rod is arranged along the axial direction of the cylinder. A guide slot is provided on the foam buoyancy disk for the support connecting rod to pass through and slide.
[0010] Furthermore, multiple support connecting rods are provided, and the support connecting rods are evenly arranged along the circumference of the foam buoyancy disk.
[0011] Furthermore, a support connecting plate is fixedly connected to the end of the support connecting rod, and the foam buoyancy plate is located between the support connecting plate and the top connecting seat.
[0012] Furthermore, the support connecting plate is detachably and fixedly connected to the end of the support connecting rod.
[0013] Furthermore, the water inlet is configured as an elongated hole extending along the axial direction of the cylinder.
[0014] Furthermore, a displacement sensor is fixedly connected to the top of the monitoring cavity, and the displacement sensor is used to detect the rise and fall displacement of the water level sensor.
[0015] The beneficial effects of this utility model are as follows: 1. By fixing a foam buoyancy plate to the top of the water level sensor, the foam buoyancy plate can drive the water level sensor to rise synchronously in the vertical direction when underground water enters the monitoring chamber of the installation cylinder and the water level rises. This ensures that the top of the water level sensor is always above the water surface, fundamentally solving the problem that traditional fixed underground monitoring equipment is easily submerged by rising water and loses its monitoring function, thus ensuring the continuous and stable operation of the equipment in waterlogged scenarios.
[0016] 2. The support connecting rods installed along the axial direction of the cylinder inside the monitoring chamber, together with the guide slots on the foam buoyancy plate, provide fixed guidance for the raising and lowering of the foam buoyancy plate and the water level sensor, preventing them from rotating, shifting or tilting during the raising and lowering process, and ensuring that the water level sensor is always in a vertical monitoring posture; at the same time, the support connecting plate at the end of the support connecting rod can provide stable support for the foam buoyancy plate and the water level sensor when there is no water accumulation or the water level is low, ensuring the accuracy of the initial monitoring position of the equipment.

[0025] The following is combined with Figures 1-4 This utility model describes an underground waterlogging monitoring device for urban areas, including an installation cylinder 1, a monitoring cavity inside the installation cylinder 1, a water inlet 102 communicating with the monitoring cavity at the bottom of the installation cylinder 1, and a balance hole 108 communicating with the monitoring cavity at the top of the installation cylinder 1.
[0026] Water level sensor 2 is installed inside the monitoring chamber to monitor the height of the water level entering the monitoring chamber.
[0027] The foam buoyancy plate 103 is fixedly connected to the top of the water level sensor 2. The foam buoyancy plate 103 raises the height of the water level sensor 2 as the water level in the monitoring chamber rises, so as to keep the top of the water level sensor 2 above the water surface.
[0028] Specifically, such as Figure 1 , Figure 4 As shown, a monitoring chamber is provided inside the mounting cylinder 1, and a water level sensor 2 is installed inside the monitoring chamber to monitor the water level entering the monitoring chamber in real time. When using the water accumulation monitoring equipment, the bottom of the mounting cylinder 1 is buried underground, and the balance hole 108 is connected to the outside. A water inlet hole 102 connected to the monitoring chamber is provided at the bottom of the mounting cylinder 1 to allow groundwater to enter the monitoring chamber. A balance hole 108 connected to the monitoring chamber is provided at the top of the mounting cylinder 1 to balance the air pressure inside and outside the monitoring chamber. A foam buoyancy plate 103 is fixedly connected to the top of the water level sensor 2. When the water level in the monitoring chamber rises, the foam buoyancy plate 103 is lifted upward under the action of buoyancy, which simultaneously drives the water level sensor 2 to rise, so as to keep the top of the water level sensor 2 above the water surface and prevent it from being submerged by the water accumulation.
[0029] Furthermore, the mounting cylinder 1 includes a cylinder body 101, a top connecting seat 301, a top cover plate 308, and a battery pack 306, with the monitoring chamber disposed within the cylinder body 101. The top connecting seat 301 is fixedly connected to the top of the cylinder body 101, and an mounting compartment 305 is formed on the top connecting seat 301, with the battery pack 306 disposed within the mounting compartment 305. The top cover plate 308 is detachably connected to the top connecting seat 301 and covers the mounting compartment 305. The battery pack 306 is connected to the water level sensor 2 via a wire 307, and the battery pack 306 is used to power the water level sensor 2.
[0030] Specifically, such as Figure 2 , Figure 3 As shown, the mounting cylinder 1 consists of a cylinder body 101, a top connecting seat 301, a top cover plate 308, and a battery pack 306. The monitoring chamber is located inside the cylinder body 101. The top connecting seat 301 is fixedly connected to the top of the cylinder body 101 by welding or riveting. An mounting compartment 305 is provided on the top connecting seat 301, and the battery pack 306 is located inside the mounting compartment 305. A wire hole for the wire 307 to pass through is provided on the top of the cylinder body 101. The top cover plate 308 is detachably connected to the top connecting seat 301 to cover the mounting compartment 305 and protect the battery pack 306. Specifically, the bottom of the top cover plate 308 is fixedly connected with multiple connecting studs 302, and the top connecting seat 301 is provided with connecting holes 303 for the connecting studs 302 to pass through respectively. One end of the connecting stud 302 passing through the connecting hole 303 is threadedly connected with a connecting nut 304. The detachable connection between the top connecting seat 301 and the top cover plate 308 is achieved through the threaded connection between the connecting nut 304 and the connecting stud 302.
[0031] Furthermore, the foam buoyancy disk 103 is configured as a ring structure, with the end of the water level sensor 2 passing through the middle of the foam buoyancy disk 103.
[0032] Specifically, such as Figure 2 , Figure 4 As shown, the foam buoyancy disk 103 is configured as a ring structure, and the end of the water level sensor 2 passes through the middle of the foam buoyancy disk 103 to realize the assembly of the foam buoyancy disk 103 and the water level sensor 2 without affecting the monitoring function of the water level sensor 2.
[0033] Furthermore, a support connecting rod 105 is fixedly connected inside the monitoring cavity. The support connecting rod 105 is arranged along the axial direction of the cylinder 101. A guide slot 104 is provided on the foam buoyancy disk 103 for the support connecting rod 105 to pass through and slide.
[0034] Furthermore, multiple support connecting rods 105 are provided, and the support connecting rods 105 are evenly arranged along the circumference of the foam buoyancy disk 103.
[0035] Specifically, such as Figure 2 , Figure 4 As shown, two support connecting rods 105 are provided and evenly arranged along the circumference of the foam buoyancy disk 103, and the support connecting rods 105 are parallel to the axis of the cylinder 101. A guide slot 104 is provided on the foam buoyancy disk 103, through which the support connecting rods 105 pass and can slide within the slot, ensuring that the foam buoyancy disk 103 rises and falls in a fixed direction, avoiding deviation and improving its stability during the rising and falling process.
[0036] Furthermore, a support connecting plate 106 is fixedly connected to the end of the support connecting rod 105, and the foam buoyancy plate 103 is located between the support connecting plate 106 and the top connecting seat 301.
[0037] Specifically, such as Figure 4 As shown, when there is no water accumulation or the water level is low, the foam buoyancy disk 103 is placed on the support connecting plate 106, and the support connecting plate 106 supports the foam buoyancy disk 103, keeping the water level sensor 2 in the initial monitoring position; when the water level rises, the foam buoyancy disk 103 can detach from the support connecting plate 106 and float upward.
[0038] Furthermore, the support connecting plate 106 is detachably and fixedly connected to the end of the support connecting rod 105.
[0039] Specifically, such as Figure 4 As shown, the support connecting plate 106 is detachably and fixedly connected to the end of the support connecting rod 105, facilitating equipment installation, disassembly, and subsequent maintenance and component replacement. Specifically, the support connecting plate 106 can be fixed to the end of the support connecting rod 105 by plugging or screwing.
[0040] Furthermore, the water inlet 102 is designed as an elongated hole extending along the axial direction of the cylinder 101. The design of the water inlet 102 as an elongated hole extending along the axial direction of the cylinder 101 increases the channel area for water to enter the monitoring chamber, accelerates the water entry speed, and enables the water level inside the monitoring chamber to quickly match the actual external water level, thereby improving the real-time monitoring performance.
[0041] Furthermore, a displacement sensor 3 is fixedly connected to the top of the monitoring cavity. The displacement sensor 3 is used to detect the rise and fall displacement of the water level sensor 2.
[0042] Specifically, such as Figure 4As shown, a displacement sensor 3 is fixedly connected to the top of the monitoring chamber. The displacement sensor 3 is used to detect the rising and falling displacement of the water level sensor 2, assisting in obtaining relevant data on water level changes and providing more reference information for water accumulation monitoring. When there is no water accumulation or the water level is low, the foam buoyancy plate 103 is placed on the support connecting plate 106, and the upward displacement of the water level sensor 2 is zero. The water height information is entirely collected by the water level sensor 2. When the water level rises, the foam buoyancy plate 103 can detach from the support connecting plate 106 and float upward. At this time, the water level information collected by the water level sensor 2 is a constant value. The water level information collected by the water level sensor 2 plus the upward displacement of the water level sensor 2 is the actual water height.
[0043] When using the waterlogging monitoring equipment, the installation cylinder 1 is completely buried in the underground pre-buried groove of the target area for waterlogging monitoring, such as low-lying urban roads and culverts. This ensures that the water inlet 102 at the bottom of the installation cylinder 1 is connected to the underground waterlogging channel or soil layer, while the balance hole 108 at the top of the installation cylinder 1 is exposed near the ground surface to ensure that the monitoring chamber is connected to the atmosphere to balance the air pressure. When the underground water increases and reaches the height of the water inlet 102, the water quickly enters the monitoring chamber through the elongated water inlet 102 at the bottom of the installation cylinder 1. As the water level in the monitoring chamber rises, the buoyancy of the foam buoyancy plate 103 gradually increases. When the buoyancy exceeds the total weight of the foam buoyancy plate 103 and the water level sensor 2, the foam buoyancy plate 103 drives the water level sensor 2 to slide upward along the guide direction of the support connecting rod 105. The cooperation between the support connecting rod 105 and the guide slot 104 ensures that there is no deviation or tilting during the lifting process, and that the top of the water level sensor 2 is always kept above the water surface to avoid being submerged by the water. Water level sensor 2 and displacement sensor 3 collect water level data in the monitoring chamber in real time, which can be uploaded to the urban flooding early warning system through a transmission module, providing multi-dimensional data support for early warning.
[0044] Where there is no conflict, the above embodiments and features described herein can be combined with each other.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
