Description

Technical Field

[0001] This utility model relates to the field of groundwater environment monitoring technology, and in particular to a groundwater environment monitoring device. Background Technology

[0002] Groundwater environment monitoring equipment is an important tool for monitoring parameters such as groundwater quality, temperature, and water level. It is of great significance for protecting groundwater resources, preventing water pollution, and rationally developing groundwater.

[0003] According to the search, the Chinese patent "A Real-time Monitoring Device for Early Warning of Groundwater Environment" authorized announcement number "CN221147700U" uses a motor, rollers, traction rope, connecting frame, sampling tube and detection components to lower the sampling tube and detection components into the groundwater to sample the groundwater and detect the groundwater temperature, thereby facilitating the monitoring of groundwater.

[0004] In the aforementioned application, because the groundwater contains large particles such as silt, the detection component is located at the bottom of the sampling tube. Under the action of water flow, large particles are easily impacted by the detection component, causing damage to the detection component and thus affecting the accuracy of groundwater temperature monitoring.

[0005] Therefore, a groundwater environment monitoring device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide groundwater environmental monitoring equipment to solve the above-mentioned problems, thereby improving the problem that large particulate impurities in water can easily damage the detection components.

[0007] This utility model achieves the above-mentioned objectives through the following technical solution: a groundwater environment monitoring device, comprising: a mounting frame, the surface of which is provided with a monitoring mechanism; and a protective mechanism, the protective mechanism including a filter cartridge and a protective sleeve at the end of the monitoring mechanism. A ring-shaped baffle is fixedly connected to the surface of the filter cartridge, a slider is slidably connected to the inner wall of the baffle, and several springs are fixedly connected to the surface of the slider, with the other end of each spring fixedly connected to the inner wall of the baffle. The filter cartridge blocks large impurities in the water from impacting the monitoring mechanism, and the protective sleeve reduces the impact force of particulate impurities on the monitoring mechanism, thereby reducing damage to the monitoring mechanism in groundwater and ensuring the accuracy of groundwater temperature monitoring. The baffle, slider, and springs effectively block large impurities adhering to the filter cartridge, preventing the outer surface of the filter cartridge from being covered by large impurities and ensuring sufficient contact between the groundwater and the monitoring mechanism.

[0008] Preferably, the monitoring mechanism includes a water level ultrasonic sensor fixedly connected to the bottom of the mounting frame, a reel rotatably connected to the inner wall of the mounting frame, a first motor fixedly connected to one side of the mounting frame, the output shaft of the first motor fixedly connected to one end of the reel, a pull rope wound around the surface of the reel, a sampling tube fixedly connected to one end of the pull rope, a storage battery fixedly connected to the bottom end of the sampling tube, a temperature sensor fixedly connected to the bottom end of the storage battery, and the top ends of the filter cartridge and the protective sleeve fixedly connected to the bottom end of the sampling tube.

[0009] Preferably, a second motor is fixedly connected to the upper end of the inner wall of the sampling cylinder, and a semi-circular block is rotatably connected to the upper end of the inner wall of the sampling cylinder, with the top end of the semi-circular block fixedly connected to the output shaft of the second motor.

[0010] Preferably, a rubber pad is fixedly connected to the surface of the barrier frame, and the surface of the slider is slidably connected to the inner wall of the rubber pad. The rubber pad prevents groundwater from flowing into the barrier frame, ensuring that the slider can slide normally within the barrier frame.

[0011] Preferably, the inner wall of the sampling cylinder is threaded with annularly distributed bolts, the surface of which is threaded onto the inner wall of the filter cylinder. These bolts facilitate the separation of the filter cylinder from the sampling cylinder, thereby simplifying filter cylinder replacement and rinsing.

[0012] Preferably, the lower end of the inner wall of the sampling cylinder is fitted with an annularly distributed elastic pad, and the bottom end of the elastic pad abuts against the top end of the bolt.

[0013] Preferably, a counterweight ring is fixedly connected to the top of the elastic pad. The elastic pad and the counterweight ring protect the bolt, preventing water from soaking into the bolt surface and reducing the likelihood of rust.

[0014] The beneficial effects of this utility model are:

[0015] 1. The filter cartridge blocks large impurities in the water from impacting the monitoring device, and the protective sleeve reduces the impact of particulate impurities on the monitoring device. Compared with existing groundwater where impurities are more likely to impact the detection components, this method blocks impurities from impacting the monitoring device, thereby reducing damage to the monitoring device in groundwater and ensuring the accuracy of groundwater temperature monitoring.

[0016] 2. By using a frame, slider, and spring, large impurities adhering to the filter cartridge are blocked, thus preventing the outer surface of the filter cartridge from being covered by large impurities and ensuring that the groundwater can fully contact the monitoring agency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In practical implementation: such as Figure 1-4 As shown, a groundwater environment monitoring device includes: a mounting frame 1, with a monitoring mechanism 2 disposed on the surface of the mounting frame 1; and a protective mechanism 3, which includes a filter cartridge 31 and a protective sleeve 32 disposed at the end of the monitoring mechanism 2. A ring-shaped grid of barriers 33 is fixedly connected to the surface of the filter cartridge 31, and a slider 34 is slidably connected to the inner wall of the barriers 33. Several springs 35 are fixedly connected to the surface of the slider 34, and the other end of each spring 35 is fixedly connected to the inner wall of the barriers 33. Both the filter cartridge 31 and the protective sleeve 32 are made of stainless steel.

[0024] like Figure 1-2As shown, the monitoring mechanism 2 includes a water level ultrasonic sensor 21 fixedly connected to the bottom of the mounting frame 1. A reel 22 is rotatably connected to the inner wall of the mounting frame 1. A first motor 24 is fixedly connected to one side of the mounting frame 1. The output shaft of the first motor 24 is fixedly connected to one end of the reel 22. A pull rope 23 is wound around the surface of the reel 22. A sampling cylinder 25 is fixedly connected to one end of the pull rope 23. A storage battery 28 is fixedly connected to the bottom end of the sampling cylinder 25. A temperature sensor 29 is fixedly connected to the bottom end of the storage battery 28. The top ends of the filter cylinder 31 and the protective sleeve 32 are both fixedly connected to the bottom end of the sampling cylinder 25. A second motor 27 is fixedly connected to the upper end of the inner wall of the sampling cylinder 25. A semi-circular block 26 is rotatably connected to the upper end of the inner wall of the sampling cylinder 25. The top end of the semi-circular block 26 is fixedly connected to the output shaft of the second motor 27. A filter screen is fixedly connected to the upper end of the inner wall of the sampling cylinder 25.

[0025] The mounting bracket 1 contains a battery, which is connected by wires to the first motor 24 and the water level ultrasonic sensor 21. Both the first motor 24 and the second motor 27 are servo motors.

[0026] Servo motors can control speed and have very accurate positioning. They can convert voltage signals into torque and speed to drive the controlled object. The rotor speed of a servo motor is controlled by the input signal and can respond quickly. In automatic control systems, they are used as actuators and have characteristics such as small electromechanical time constant and high linearity. They can convert the received electrical signals into angular displacement or angular velocity output on the motor shaft.

[0027] When groundwater monitoring is required, the mounting bracket 1 is installed at the location to be monitored using screws. The ultrasonic water level sensor 21 is then automatically activated. The ultrasonic water level sensor 21 emits ultrasonic signals through its internal transmitter. These signals are reflected back after encountering the surface of the groundwater and are received by the receiver, which converts them into electrical signals. The processor inside the ultrasonic water level sensor 21 calculates the water level height based on the transmission and reception time of the ultrasonic signals, as well as parameters such as the speed of sound. The detected groundwater level height is then transmitted to the remote monitoring center, allowing staff to understand the groundwater level in a timely manner.

[0028] The first motor 24 and temperature sensor 29 are automatically activated. The output shaft of the first motor 24 rotates, driving the reel 22 to rotate. The rotating reel 22 loosens the pull rope 23, causing the sampling tube 25 to fall into the groundwater. After the sampling tube 25 falls to a suitable depth, the first motor 24 is automatically turned off. At this time, the temperature sensor 29 monitors the temperature of the groundwater. The temperature sensing element inside the temperature sensor 29 will reach thermal equilibrium with the groundwater, thus reflecting the temperature of the groundwater. The monitored groundwater temperature data is transmitted to the remote monitoring center, allowing staff to understand the groundwater temperature in a timely manner.

[0029] When groundwater needs to be sampled, the second motor 27 is manually turned on. The output shaft of the second motor 27 rotates, causing the semicircular block 26 to rotate. The second motor 27 is then manually turned off, opening the top of the sampling tube 25. At this time, the groundwater flows into the sampling tube 25. After sampling is completed, the output shaft of the second motor 27 is manually turned on again, causing the semicircular block 26 to rotate and seal the top of the sampling tube 25. The second motor 27 is then manually turned off. At this time, the output shaft of the first motor 24 rotates, pulling the sampling tube 25 upward through the reel 22 and the pull rope 23, thereby causing the sampling tube 25 to detach from the groundwater. Water samples can then be taken out from the sampling tube 25 for subsequent testing.

[0030] like Figure 3 As shown, a rubber pad 36 is fixedly connected to the surface of the frame 33, and the surface of the slider 34 is slidably connected to the inner wall of the rubber pad 36.

[0031] As the groundwater flows, it carries impurities that impact the slider 34 and the baffle 33. The impact on the slider 34 compresses the spring 35. When the impact force decreases, the elastic force of the spring 35 pushes the slider 34 to reset, preventing large impurities from adhering to the filter cartridge 31. The filter cartridge 31 prevents large impurities in the water from impacting the temperature sensor 29. Groundwater and small particulate impurities flow into the interior of the filter cartridge 31. At this time, the protective sleeve 32 prevents the groundwater and small particles from impacting the temperature sensor 29.

[0032] like Figure 4 As shown, the inner wall of the sampling cylinder 25 is threaded with annularly distributed bolts 37. The surface of the bolts 37 is threaded to the inner wall of the filter cylinder 31. Annularly distributed elastic pads 38 are snapped into the lower end of the inner wall of the sampling cylinder 25. The bottom end of the elastic pads 38 abuts against the top end of the bolts 37. A counterweight ring 39 is fixedly connected to the top end of the elastic pads 38. The elastic pads 38 are made of silicone.

[0033] When the filter cartridge 31 needs to be rinsed, pull the counterweight ring 39 to move the elastic pad 38 away from the sampling cylinder 25. At this time, use an electric screwdriver to move the bolt 37 away from the filter cartridge 31 and pull the filter cartridge 31 to remove and rinse it.

[0034] When this utility model is in use, the flowing groundwater carries impurities that impact the slider 34 and the frame 33. The slider 34 is impacted and compresses the spring 35. When the impact force decreases, the elastic force of the spring 35 pushes the slider 34 to reset, preventing large impurities from adhering to the filter cartridge 31. The filter cartridge 31 prevents large impurities in the water from impacting the temperature sensor 29. Groundwater and small particulate impurities flow into the interior of the filter cartridge 31. At this time, the protective sleeve 32 prevents the groundwater and small particles from impacting the temperature sensor 29.

[0035] It should be noted that the mounting bracket 1, water level ultrasonic sensor 21, pull rope 23, first motor 24, second motor 27, storage battery 28, temperature sensor 29, spring 35, bolt 37, and counterweight ring 39 mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the water level ultrasonic sensor 21, first motor 24, second motor 27, storage battery 28, and temperature sensor 29 can be powered by the built-in power supply or by mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art. 。
