Description

Technical Field

[0001] This utility model relates to the field of drainage technology in mining areas, specifically to an automatic drainage device for water storage tanks. Background Technology

[0002] Natural rainfall and groundwater seepage in mining areas are serious factors threatening the safety of open-pit mining operations. Especially during the annual flood season, the inability to quickly drain accumulated water from the mining area directly threatens the lives of miners and the safety of production equipment, causing significant property losses to the enterprise. Water storage tanks are essential for ensuring the continuous operation of drainage pumps; monitoring their levels ensures the normal operation of the pumps and prevents overflow.

[0003] Traditional mine water storage ponds are typically equipped with water level gauges, allowing for manual drainage based on the displayed water level. During the rainy season, 24-hour on-site monitoring of the water level is required, with drainage necessary to maintain the water level. However, during heavy rains, the field of vision is obstructed, making it difficult to monitor the water level in real time. If the water level is too high and overflows the storage pond, it can lead to the danger of flooding production equipment.

[0004] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Utility Model Content

Detailed Implementation

[0022] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figure 1 As shown, Figure 1 This is a structural view of the connection device used to collect asphalt production flue gas.

[0025] The automatic drainage device for a water storage tank according to this utility model includes a level gauge 1, a mounting bracket 2, and a controller. The level gauge 1 is fixedly installed on the water storage tank through the mounting bracket 2. The level gauge 1 is connected to the controller via data connection. The controller is connected to the drain valve or alarm of the water storage tank.

[0026] An alarm threshold or a drainage threshold is set in the controller. When the level gauge 1 detects the water level information of the water storage tank and transmits it to the controller, the controller reads the water level information and compares it with the alarm threshold or the drainage threshold. When the alarm threshold is reached, the controller triggers an alarm through the alarm device, and the water level can be controlled by manual drainage. When the drainage threshold is reached, the controller opens the drain valve to drain the water storage tank, thereby achieving automatic drainage.

[0027] Preferably, the level gauge 1 is an ultrasonic level gauge for non-contact water level monitoring, and the ultrasonic level gauge can be wirelessly connected to the controller via WiFi or other means.

[0028] This invention uses the level gauge 1 to monitor the water level in the reservoir in real time, thereby achieving intelligent monitoring, enabling high water level warnings or automated drainage water level control, avoiding the impact of rain on water level monitoring, and thus effectively controlling the water level of the reservoir.

[0029] Example 2

[0030] The mounting bracket 2 includes a fixed pipe 21, which is a hollow cylindrical straight pipe. The fixed pipe 21 is vertically installed in the water storage tank. The level gauge 1 is installed at the top of the fixed pipe 21, and the probe of the level gauge 1 is installed inside the fixed pipe 21. The fixed pipe 21 is in communication with the water storage tank. The water level of the water storage tank can be detected by detecting the water level in the fixed pipe 21 through the level gauge 1, thereby reducing the impact of large fluctuations in the water level of the water storage tank or rainwater between the water level of the water storage tank and the probe on the detection of the level gauge 1.

[0031] Specifically, the mounting bracket 2 further includes a first connecting flange 22, which is annular and is sealed and fixed to the top end of the fixed pipe 21. The first connecting flange 22 is annularly provided with a mounting hole 221. The level gauge 1 is fixedly mounted on the first connecting flange 22 by mounting bolts 11 and the mounting hole 221. The probe of the level gauge 1 is set in the central hole 222 of the first connecting flange 22 so as to extend into the fixed pipe 21 for detection.

[0032] The mounting bracket 2 also includes a cover plate 23, which is a cylindrical tube with a sealed end and an open end at its two ends. The sealed end is sealed with a sealing plate, and the inner wall of the open end is provided with a first thread. A connecting ring 24 is provided on the first connecting flange 22, and the connecting ring 24 and the first connecting flange 22 are coaxially arranged. The outer wall of the connecting ring 24 is provided with a second thread. The open end and the connecting ring 24 are detachably connected through the first thread and the second thread, so that the level gauge 1 can be covered inside the cover plate 23 to protect the level gauge 1 from being damaged by rainwater.

[0033] Preferably, multiple water level scales are vertically arranged on the outer circular wall of the fixed pipe 21. The real-time water level of the water storage tank can be observed manually through the water level scales. Calibration and alignment can be performed by comparing the manual observation with the detection value of the liquid level gauge 1, thereby ensuring the accuracy of the automatic drainage or alarm of this utility model.

[0034] Example 3

[0035] A vent hole 26 is provided on the upper side wall of the fixed pipe 21, and a flow hole 27 is provided at the lower part of the fixed pipe 21. Both the vent hole 26 and the flow hole 27 are connected to the inside and outside of the fixed pipe 21. Water in the water storage tank can flow in and out of the fixed pipe 21 through the flow hole 27 to achieve the same level between the water level in the water storage tank and the liquid level in the fixed pipe 21. When the liquid level in the fixed pipe 21 changes, the vent hole 26 can allow air to enter or exit the fixed pipe 21 to ensure the stability of the air pressure in the fixed pipe 21, thereby further ensuring the same level between the water level in the water storage tank and the liquid level in the fixed pipe 21.

[0036] Generally, the fixed pipe 21 is provided with a second connecting flange 25, which has a connecting hole. The second connecting flange 25 is fixed to the bottom or side wall of the water storage tank through the connecting hole and expansion bolts, thereby fixing the fixed pipe 21 in the water storage tank.

[0037] Example 4

[0038] In this embodiment, the expansion bolts are fixedly installed at the bottom of the water storage tank, the second connecting flange 25 is annular and is fixedly sleeved on the bottom of the fixed pipe 21, the connecting holes are evenly distributed in a ring around the fixed pipe 21, thereby achieving the stable installation of the fixed pipe 21 in the water storage tank, and the flow hole 27 is provided on the side wall of the fixed pipe 21.

[0039] Preferably, a plurality of the flow holes 27 are arranged vertically along the fixed tube 21, and a barrier sleeve 28 is provided outside the fixed tube 21. The barrier sleeve 28 is coaxially sleeved outside the fixed tube 21, and the upper end of the barrier sleeve 28 is sealed and fixed on the outer wall of the fixed tube 21 by a barrier ring 29. All the flow holes 27 are provided inside the barrier sleeve 28.

[0040] Since the bottom of the fixed pipe 21 is fixed, the internal and external flow of the fixed pipe 21 is mainly through the flow hole 27. The flow hole 27 is set at each height to ensure that the internal and external flow of the fixed pipe 21 is relatively fast. At this time, the flow hole 27 near the liquid surface is prone to drastic changes in the liquid level in the fixed pipe 21 under the impact of the water flow in the water storage tank. Especially during the rainy season when the water flow is large, the alarm or drainage valve will be frequently triggered when it is near the alarm threshold or the drainage threshold, which can easily cause equipment damage. The setting of the barrier sleeve 28 allows the water flow to enter through the lower end of the barrier sleeve 28 and flow into the fixed pipe 21 through the flow hole 27, which effectively reduces the impact force of the water flow in the water storage tank and makes the liquid level change in the fixed pipe 21 more stable.

[0041] Example 5

[0042] In this embodiment, the expansion bolts are fixedly installed on the side wall of the water storage tank. The second connecting flange 25 includes a first connecting plate 251 and a second connecting plate 252. The first connecting plate 251 is sleeved and fixedly installed on the outer wall of the fixed pipe 21. The first connecting plate 251 and the second connecting plate 252 are vertically fixed to form a T-shaped or L-shaped second connecting flange 25. The second connecting plate 252 is provided with the connecting hole, thereby realizing the stable installation of the fixed pipe 21 in the water storage tank. The bottom of the fixed pipe 21 is open to form the flow hole 27.

[0043] Preferably, multiple second connecting flanges 25 can be provided according to the length of the fixing pipe 21 to fix the fixing pipe 21 on the side wall of the water storage tank.

[0044] Water can only flow into the fixed pipe 21 through the lower end of the fixed pipe 21, which effectively reduces the impact force of the water flow in the water storage tank and makes the liquid level change in the fixed pipe 21 more stable.

Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
