Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, specifically, it relates to a monitoring sensor. Background Technology

[0002] Water is an important part of the human living environment and an essential resource for life and production. In the second half of the 21st century, with the overexploitation and abuse of various natural resources, environmental pollution has become increasingly severe. Large amounts of sewage discharged from production and daily life have seriously polluted water resources. It is necessary to test the water quality before using polluted water.

[0003] Chinese patent CN219224761U discloses a monitoring sensor, including a water quality sensor and a protective shell. The water quality sensor is set inside the protective shell, and a pair of connecting blocks are fixedly connected to the inner side wall of the protective shell. The pair of connecting blocks are symmetrically arranged, and a slide rail is opened in the connecting block. A slider is slidably connected in the slide rail. A float plate is fixedly connected to the end of the slider away from the slide rail. By setting a cleaning sponge on the sensor and installing the cleaning sponge on the float plate, the float plate will float up and down in the slide rail after being impacted by water. When it floats, it drives the cleaning sponge to move, and the cleaning sponge can clean the sensor when it moves, which facilitates the cleaning of the sensor. However, the floating of the float plate depends on the impact of water flow and the change of buoyancy of water. If the water flow is too stable or the water flow speed is too high, the float plate may not be able to float up and down stably as expected, thus affecting the cleaning effect of the cleaning sponge on the sensor.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a monitoring sensor that solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A monitoring sensor includes: a sensor body and a protective shell. A top cover is connected to the top of the protective shell. The bottom of the sensor body penetrates through and is connected to the top cover. The bottom of the sensor body is located inside the protective shell. Limiting blocks are connected to the four corners of the inner wall of the protective shell. A filtering mechanism is connected to the bottom of the protective shell. A float plate is located inside the protective shell through the limiting blocks. A through hole is opened at the center of the float plate. The sensor body passes through the through hole. A limiting groove is opened on the inner wall of the through hole on the float plate. Multiple adsorption balls are connected in the limiting groove and abut against the sensor body. A guide plate is located below the limiting blocks and is V-shaped. The opening of the guide plate faces the sensor body. The front and rear ends of the guide plate are connected to the inner wall of the protective shell, and there are gaps between the left and right ends and the inner wall of the protective shell.

[0008] Optionally, the filtration mechanism includes a filter basket fixedly connected to the bottom of the protective shell, and a filter screen is connected to the lower middle part of the inner wall of the protective shell, with the filter screen located above the filter basket.

[0009] Optionally, the diameter of the filter holes on the surface of the filter screen is smaller than the diameter of the filter holes on the surface of the filter basket.

[0010] Optionally, notches are provided at the four corners of the surface of the floating plate, and the notches are adapted to the limiting blocks.

[0011] Optionally, a slider is connected to the notch, and a groove is formed on the surface of the limiting block, with the slider located in the groove.

[0012] Optionally, the adsorption ball is rotatably connected to the limiting groove, and two adjacent adsorption balls abut against each other.

[0013] Optionally, the float plate has an inner cavity, in which a cleaning ring is connected. The cleaning ring abuts against the other end of the adsorption ball, and a cleaning brush is connected to the surface of the end of the cleaning ring that abuts against the adsorption ball.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] 1. By setting up adsorption balls, the adsorption balls on the floating plate come into frictional contact with the surface of the sensor body. As the floating plate floats up and down, the adsorption balls can continuously adsorb impurities on the surface of the sensor body. At the same time, the adsorption balls are rotatably connected to the limiting groove and adjacent to each other, and can rotate on their own, making full use of the surface to adsorb impurities, which greatly improves the cleaning efficiency and ensures that the sensor surface is thoroughly cleaned.

[0016] 2. By setting a cleaning ring that abuts against the adsorption ball and has a cleaning brush on it, the adsorption ball can brush off the surface impurities in time after adsorbing them, so that the adsorption ball can maintain good adsorption performance and thus continuously and effectively clean the sensor body, ensuring the long-term effectiveness of the self-cleaning function.

[0017] 3. By setting up a guide plate, the "V"-shaped guide plate guides the water flow to split to both sides and then acts on the float plate, ensuring that the float plate is subjected to a stable water flow impact force, making the float plate float up and down more stably and effectively, thereby driving the adsorption ball to better clean the sensor body and improve the stability of the entire device operation.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figure 1-5 As shown, this embodiment provides a monitoring sensor, including: a sensor body 1 and a protective shell 2. The top of the protective shell 2 is connected to a top cover 3. The bottom of the sensor body 1 passes through the top cover 3 and is connected to the top cover 3. The bottom of the sensor is located inside the protective shell 2. Limiting blocks 5 are connected to the four corners of the inner wall of the protective shell 2. A filtering mechanism is connected to the bottom of the protective shell 2. A float plate 4 is located inside the protective shell 2 through the limiting blocks 5. A through hole 11 is opened at the center of the float plate 4. The sensor body 1 passes through the through hole 11. A limiting groove 12 is opened on the inner wall of the through hole 11. Multiple adsorption balls 13 are connected in the limiting groove 12 and abut against the sensor body 1. A guide plate 15 is located below the limiting blocks 5 and is V-shaped. The opening of the guide plate 15 faces the sensor body 1. The front and rear ends of the guide plate 15 are connected to the inner wall of the protective shell 2, and there are gaps between the left and right ends and the inner wall of the protective shell 2.

[0030] The sensor body 1 is the core component of the entire device used for water quality monitoring. The top cover 3 connected to the top of the protective shell 2 serves to fix the position of the sensor body 1. The bottom of the sensor body 1 passes through the top cover 3 and is connected to it, so that the bottom part of the sensor is located inside the protective shell 2. This ensures that the sensor can monitor the water inside the protective shell 2, and the top cover 3 stabilizes it at the top of the protective shell 2, preventing it from swaying in the water and affecting the monitoring accuracy. The limiting blocks 5 are used to limit the position of the float 4 inside the protective shell 2, preventing it from swaying or shifting. On the other hand, they provide support points for the installation and positioning of the float 4. The filter mechanism connected to the bottom of the protective shell 2 performs preliminary filtration of the water entering the protective shell 2. Through the filter mechanism, larger impurities in the water can be blocked from entering, preventing these impurities from directly contacting the sensor body 1, thereby reducing the impact of impurities on sensor performance and extending the sensor's service life. The float 4... The limit block 5 is installed inside the protective shell 2 and can float up and down in the water inside the protective shell 2, allowing the float plate 4 to move relative to the sensor body 1. When the float plate 4 floats up and down under the action of water flow, the adsorption ball 13 will move with the float plate 4 and make frictional contact with the surface of the sensor body 1. Utilizing the adsorption characteristics of the adsorption ball 13, impurities on the surface of the sensor body 1 are adsorbed, thereby achieving the purpose of cleaning the sensor and ensuring the monitoring accuracy of the sensor. The front and rear ends of the guide plate 15 are connected to the inner wall of the protective shell 2, while there are gaps between the left and right ends and the inner wall of the protective shell 2. After the water flow enters the protective shell 2, it will be guided by the "V"-shaped guide plate 15. The water flow is split to both sides according to the shape of the guide plate 15 and then acts on the float plate 4 at the same time, ensuring the stability of the water flow impact force on the float plate 4, so that the float plate 4 can float up and down more stably and effectively, thereby driving the adsorption ball 13 to better clean the sensor body 1.

[0031] In this embodiment, the filtration mechanism includes a filter basket 7 fixedly connected to the bottom of the protective shell 2. A filter screen 6 is connected to the lower middle part of the inner wall of the protective shell 2. The filter screen 6 is located above the filter basket 7. The diameter of the filter holes on the surface of the filter screen 6 is smaller than the filter holes on the surface of the filter basket 7. The filter basket 7 is fixedly connected to the bottom of the protective shell 2 and is the primary filtration component of the filtration system. Because it is located at the bottom of the protective shell 2, water flows through the filter basket 7 first after entering the protective shell 2. Larger impurities, such as leaves and branches, are intercepted by the filter basket 7, preventing these large particles from entering the interior of the protective shell 2 and avoiding damage to the sensor. If components such as body 1 and float plate 4 become clogged or damaged, the filter screen is located above the filter basket 7. The diameter of the filter holes on the surface of the filter screen 6 is smaller than that on the surface of the filter basket 7. The water that has been initially filtered by the filter basket 7 will undergo secondary filtration by the filter screen 6 as it flows upward. The filter screen 6 can further intercept smaller particulate impurities in the water, such as sand and algae, and further purify the water quality that enters the protective shell 2 and comes into contact with the sensor body 1. This ensures that only finer impurities or substances dissolved in the water can approach the sensor body 1, thereby minimizing the impact of impurities on the sensor's monitoring accuracy.

[0032] Notches 8 are provided at the four corners of the surface of the float plate 4, and the notches 8 are adapted to the limiting blocks 5, so that the float plate 4 can be accurately positioned inside the protective shell 2, limiting the position of the float plate 4 in the horizontal direction, preventing the float plate 4 from shifting or shaking under the impact of water flow, and ensuring that the adsorption ball 13 on the float plate 4 can always accurately contact the sensor body 1 and perform the cleaning function. A slider 9 is connected to the notch 8, and a groove 10 is provided on the surface of the limiting block 5. The slider 9 is located in the groove 10. When the water flow impacts the float plate 4, the float plate 4 can float up and down stably under the guidance of the groove 10, which enhances the stability and controllability of the movement of the float plate 4, and ensures that the float plate 4 can perform the cleaning operation of the sensor body 1 as expected under different water flow conditions.

[0033] The adsorption ball 13 is rotatably connected to the limiting groove 12, and two adjacent adsorption balls 13 abut against each other. When the adsorption ball 13 contacts the sensor body 1, it can not only move along the surface of the sensor body 1 with the up and down floating of the float plate 4, but also rotate during the friction with the surface of the sensor body 1. This helps the adsorption ball 13 to use its surface to adsorb impurities in all directions, improve adsorption efficiency, and also wear more evenly, extending the service life of the adsorption ball 13. The float plate 4 has an inner cavity, in which a cleaning ring 14 is connected. The cleaning ring 14 abuts against the other end of the adsorption ball 13. A cleaning brush is connected to the surface of the end of the cleaning ring 14 that abuts against the adsorption ball 13. When the adsorption ball 13 adsorbs impurities with the movement of the float plate 4, the cleaning brush on the cleaning ring 14 will contact the surface of the adsorption ball 13. During the movement of the float plate 4, the cleaning brush can clean the surface of the adsorption ball 13, brushing off some of the impurities attached to the surface of the adsorption ball 13, so that the adsorption ball 13 can maintain good adsorption performance and continuously and effectively clean the sensor body 1.

[0034] Working principle:

[0035] When the protective shell 2 is placed in water, water enters the protective shell 2 and comes into contact with the sensor body 1. The sensor body 1 then performs its monitoring function, detecting water quality-related parameters, thereby achieving water quality monitoring.

[0036] When water enters from the bottom of the protective shell 2, larger impurities, such as leaves and branches, will be intercepted by the filter basket 7 first. After the water is initially filtered by the filter basket 7, it continues to flow upward. At this time, the filter screen 6 will further intercept smaller particulate impurities in the water, such as sand and algae, to perform secondary purification of the water quality, ensuring that only smaller impurities or substances dissolved in the water can approach the sensor body 1, minimizing the impact of impurities on the sensor's monitoring accuracy.

[0037] When water flows onto the float plate 4, the float plate 4 floats up and down, causing the adsorption balls 13 to move along with it. During this movement, the adsorption balls 13 come into frictional contact with the surface of the sensor body 1, using their own adsorption properties to adsorb impurities from the surface of the sensor body 1, thereby cleaning the sensor and ensuring its monitoring accuracy. After the adsorption balls 13 adsorb impurities as they move with the float plate 4, the cleaning brush comes into contact with the surface of the adsorption balls 13. During the movement of the float plate 4, the cleaning brush brushes off some of the impurities attached to the surface of the adsorption balls 13, maintaining good adsorption performance and continuously and effectively cleaning the sensor body 1. This utility model is not limited to the above-described embodiments. Anyone should understand that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technologies, shapes, and structures not described in detail in this utility model are all known technologies.
