Description

Technical Field

[0001] This utility model relates to the field of sewage treatment, specifically to a waterproof and alarm structure for an outdoor sleeve-type sludge discharge valve. Background Art

[0002] In the field of wastewater treatment, the sleeve sludge discharge valve is one of the key pieces of equipment in the wastewater treatment system. Its main function is to periodically discharge sludge to ensure the efficiency of subsequent deep wastewater treatment. Currently, patent research on sleeve sludge discharge valves focuses on controlling and regulating sludge discharge flow, preventing clogging, and preventing sludge leakage. However, electric sleeve sludge discharge valves installed outdoors typically face the following problems during actual operation:

[0003] 1. Due to the defects in waterproofing of traditional designs, especially in rainy or humid environments, the valve body is prone to water leakage or water accumulation. This not only leads to failure of internal electrical components and reduces service life, but also affects the efficiency of mud and water discharge and the normal operation of the equipment, making maintenance work complicated and causing inconvenience and safety hazards to operators.

[0004] 2. Outdoor-installed sleeve-type mud discharge valves are more susceptible to the effects of ambient temperature and humidity. Excessive humidity may occur inside the valve body, leading to a decline in valve performance or even failure. Existing mud discharge valves typically lack real-time monitoring and alarm functions for internal temperature, humidity, and dew point temperature, thus making it impossible to take timely preventative measures under adverse environmental conditions.

[0005] 3. As the mud discharge valve ages, the valve opening value becomes increasingly blurry on the LCD display. Furthermore, due to the low installation height of the display screen, operators must repeatedly crouch down to observe and confirm the readings during inspections. These two issues make it difficult for inspectors to easily confirm the valve's opening status, potentially affecting the equipment's adjustment accuracy.

[0006] Therefore, how to provide a waterproof design for an outdoor sleeve mud discharge valve, so as to effectively alleviate water accumulation inside the valve body, improve the equipment fault monitoring and early warning capabilities, reduce the frequency of later maintenance, and ensure the long-term stable operation of the system, is the technical problem that this utility model urgently needs to solve.

[0016] The waterproof and alarm structure of the outdoor sleeve mud discharge valve provided by this utility model may also have the following features: the top of the sleeve is sealed, and the sleeve is a transparent polycarbonate sleeve.

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

[0018] The waterproof and alarm structure of the outdoor sleeve-type mud discharge valve provided by this utility model includes a sleeve and a valve body, which are connected. A lead screw is installed inside the sleeve, and a valve opening scale is mounted on its surface. A temperature and humidity sensor, an alarm element, and a controller are installed inside the valve body. A waterproof ring is installed on the sleeve near the valve body, and the temperature and humidity sensor and alarm element are electrically connected to the controller. Based on this waterproof and alarm structure of the sleeve-type mud discharge valve, the waterproof ring on the sleeve provides a certain degree of waterproofing, and the valve opening scale on the outer surface of the sleeve visually displays the percentage of valve opening. Furthermore, the mud discharge valve can detect the temperature and humidity inside the valve body through the temperature and humidity sensor, and then, through calculation and control by the controller, trigger an alarm when the temperature and humidity inside the valve body exceed a certain threshold. This improves the fault detection and early warning capabilities of the entire device, providing greater convenience for the inspection of the mud discharge valve, reducing the frequency of subsequent maintenance, and ensuring the long-term stable operation of the mud discharge valve.

[0019] In addition, a screw plate is provided near the bottom of the sleeve, and a groove is provided at the lower part of the screw plate. The waterproof ring is placed in the groove, and the inner wall of the waterproof ring is tightly fitted with the groove, thereby ensuring the waterproof ring's waterproof performance for the sleeve.

[0020] In addition, the temperature and humidity sensor and the alarm element are connected to the controller via pins, and a resistor is connected in series on the pins connecting the temperature and humidity sensor to the controller. This series resistor is used to prevent the sensor element from burning out due to excessive current.

[0021] In addition, the temperature and humidity sensor and alarm element are located on the inner wall of the valve body cavity and close to the electrical control main board. This arrangement ensures that the temperature and humidity sensor and alarm element can obtain more representative and accurate parameter data.

[0022] Furthermore, the alarm element will sound when the temperature inside the valve body exceeds a certain threshold or when the dew point temperature inside the valve body exceeds the ambient temperature. Utilizing a dual-monitoring mechanism of humidity and dew point temperature allows for more sensitive and accurate monitoring of the equipment's internal environment, facilitating early warnings and timely handling of equipment problems, thereby reducing the risk of equipment failure.

[0023] In addition, in this invention, the formula for calculating the dew point temperature is related to the ambient temperature, and can be adaptively adjusted according to the climate conditions of different regions, ensuring that the outdoor sleeve mud discharge valve can adapt to various environmental conditions.

[0024] Furthermore, the controller is also connected to an external control terminal, which can control and turn on / off the detection frequency of the temperature and humidity sensor and the alarm of the alarm element.

[0025] In addition, since the sleeve has a valve opening scale on its surface, the original valve opening observation port at the top of the sleeve has been sealed, effectively sealing the position where water could easily enter, thus enhancing the overall waterproof performance of the mud discharge valve and ensuring long-term dryness inside the valve body.

[0030] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] This outdoor sleeve sludge discharge valve is used in sewage treatment to periodically discharge sludge.

[0032] like Figures 1-3 As shown, the outdoor sleeve-type mud discharge valve includes a sleeve 100 and a valve body 200. The sleeve 100 is installed at the top of the valve body 200 and is located above the valve body 200.

[0033] The sleeve 100 is a transparent polycarbonate sleeve resistant to long-term ultraviolet radiation, and contains a lead screw 101. The bottom end of the sleeve has an upper circular groove 102 and a lower circular groove 103 at its connection with the valve body 200. The lower end of the lead screw 101 protrudes from the bottom of the lower circular groove 103. A handwheel 104 is also provided on the upper circular groove 102.

[0034] In addition, a screw plate 105 for connection is provided on the sleeve 100 near the upper circular groove 102, and the screw plate 105 is provided with a number of screw holes 106.

[0035] The bottom of the screw plate 105 is provided with a groove 107, and a waterproof ring 108 is provided in the groove 107. The waterproof ring 108 is made of high elastic silicone, and the outer ring of the waterproof ring 108 fits against the inner wall of the upper circular groove 102, while the inner ring fits tightly against the groove 107, ensuring the waterproof performance at this location.

[0036] In addition, a valve opening gauge 109 is provided on the outer surface of the sleeve 100, which is located at the original observation port of the valve opening on the sleeve 100. By setting the valve opening gauge 109, the original observation port of the valve opening is sealed, further ensuring the waterproof performance of the sleeve 100.

[0037] The valve body 200 is connected to a motor 201, and a switching handle 202 is provided on one side of it. The manual or electric rotation of the lead screw 101 inside the valve body 200 can be switched by the switching handle 202.

[0038] The valve body 200 has a cavity inside, in which an open-source development circuit board 210, an electrical control main board 220, a temperature and humidity sensor 230, an alarm element 240, and a controller 250 are installed.

[0039] The open-source development board 210 is equipped with a power interface 211 and a data interface 212. The controller 250 is mounted on the open-source development board 210. In addition, the controller 250 is connected to a GND pin 213, a digital output pin 214, a VCC pin 215, and a data input pin 216.

[0040] The power interface 211 connects to an external power supply, providing a stable 5V operating voltage for the open-source development board 210.

[0041] Data interface 212 connects to the spare terminal block of the bus and connects to the control terminal 217 (computer end) in the external control room.

[0042] The GND pin 213 and digital output pin 214 of the controller 250 are connected to the alarm element 240, respectively. In addition, the GND pin 213 of the controller 250 is the signal ground terminal.

[0043] The VCC pin 215 and data input pin 216 of the controller 250 are connected to the temperature and humidity sensor 230, and a resistor 217 is connected in series between the temperature and humidity sensor 230 and the two pins. The temperature and humidity sensor 230 transmits the detected ambient temperature and humidity data inside the valve body 200 to the data input pin 216 of the controller 250. The VCC pin 215 is the power supply voltage terminal for the controller 250.

[0044] In addition, the electrical control main board 220 is also installed in the cavity of the valve body 200. The temperature and humidity sensor 230 and the alarm element 240 are respectively installed on the inner wall of the cavity of the valve body 200, close to the electrical control main board 220, in order to obtain more accurate parameter data.

[0045] In the aforementioned waterproof and alarm structure, the alarm operation principle is as follows:

[0046] The temperature and humidity sensor 230 first detects the ambient temperature and humidity data inside the valve body 200 and transmits them to the controller 250;

[0047] When environmental conditions trigger an alarm (humidity greater than 90% ± 5% or dew point temperature greater than ambient temperature), the controller 250 controls the alarm element 240 to issue an alarm warning, reminding the on-duty personnel to conduct on-site inspection and handle the situation.

[0048] In addition, in this embodiment, the threshold for judging humidity data is 90% ± 5%. In other embodiments, it can be adjusted adaptively according to different environments.

[0049] Moreover, in the above working principle, the detection frequency of the temperature and humidity sensor 230 and whether the alarm warning of the alarm element 240 is working can be controlled and adjusted by the external control terminal 217.

[0050] The waterproof and alarm structure of the outdoor sleeve-type mud discharge valve in the above embodiment includes a sleeve and a valve body, which are connected. A lead screw is installed inside the sleeve, and a valve opening scale is mounted on its surface. A temperature and humidity sensor, an alarm element, and a controller are installed inside the valve body. A waterproof ring is located on the sleeve near the valve body, and the temperature and humidity sensor and alarm element are electrically connected to the controller. Based on this waterproof and alarm structure, the sleeve-type mud discharge valve provides a certain degree of waterproofing by installing a waterproof ring on the sleeve. Furthermore, the valve opening scale on the outer surface of the sleeve visually displays the percentage of valve opening. In addition, the mud discharge valve can detect the temperature and humidity inside the valve body using the temperature and humidity sensor. Through calculation and control by the controller, when the temperature and humidity inside the valve body exceed a certain threshold, an alarm is triggered by the alarm element. This improves the fault detection and early warning capabilities of the entire device, providing greater convenience for the inspection of the mud discharge valve, reducing the frequency of subsequent maintenance, and ensuring the long-term stable operation of the mud discharge valve.

[0051] In addition, a screw plate is provided near the bottom of the sleeve, and a groove is provided at the lower part of the screw plate. The waterproof ring is placed in the groove, and the inner wall of the waterproof ring is tightly fitted with the groove, thereby ensuring the waterproof ring's waterproof performance for the sleeve.

[0052] In addition, the temperature and humidity sensor and the alarm element are connected to the controller via pins, and a resistor is connected in series on the pins connecting the temperature and humidity sensor to the controller. This series resistor is used to prevent the sensor element from burning out due to excessive current.

[0053] In addition, the temperature and humidity sensor and alarm element are located on the inner wall of the valve body cavity and close to the electrical control main board. This arrangement ensures that the temperature and humidity sensor and alarm element can obtain more representative and accurate parameter data.

[0054] Furthermore, the alarm element will sound when the temperature inside the valve body exceeds a certain threshold or when the dew point temperature inside the valve body exceeds the ambient temperature. Utilizing a dual-monitoring mechanism of humidity and dew point temperature allows for more sensitive and accurate monitoring of the equipment's internal environment, facilitating early warnings and timely handling of equipment problems, thereby reducing the risk of equipment failure.

[0055] In addition, in this invention, the formula for calculating the dew point temperature is related to the ambient temperature, and can be adaptively adjusted according to the climate conditions of different regions, ensuring that the outdoor sleeve mud discharge valve can adapt to various environmental conditions.

[0056] Furthermore, the controller is also connected to an external control terminal, which can control and turn on / off the detection frequency of the temperature and humidity sensor and the alarm of the alarm element.

[0057] In addition, since the sleeve has a valve opening scale on its surface, the original valve opening observation port at the top of the sleeve has been sealed, effectively sealing the position where water could easily enter, thus enhancing the overall waterproof performance of the mud discharge valve and ensuring long-term dryness inside the valve body.

[0058] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
