Description

Technical Field

[0001] The invention relates to the field of sewage treatment, and in particular to a waterproof and alarm structure of an outdoor sleeve mud discharge valve. Background Art

[0002] In the field of sewage treatment, the sleeve mud valve is one of the key equipment in the sewage treatment system. Its main function is to discharge sludge regularly to ensure the efficiency of subsequent sewage deep treatment. At present, the patent research on the sleeve mud valve focuses on controlling and regulating the mud discharge flow, preventing blockage and preventing mud and water leakage. However, the electric sleeve mud valve installed outdoors usually faces the following problems during actual operation:

[0003] 1. Due to the defects of traditional design in waterproofing, especially in rainy or humid environments, the valve body is prone to water seepage or accumulation, which not only causes internal electrical failures and reduces service life, but also affects the muddy water discharge efficiency and the normal operation of the equipment, making maintenance work complicated and bringing inconvenience and safety hazards to operators.

[0004] 2. Sleeve drain valves installed outdoors are more susceptible to the influence of ambient temperature and humidity. Excessive humidity may occur inside the valve body, causing valve performance degradation or even failure. Existing drain valves usually do not have real-time monitoring and alarm functions for temperature, humidity and dew point temperature inside the valve body, so it is impossible to take preventive measures in time under adverse environmental conditions.

[0005] 3. As the mud valve ages, the valve opening value on the LCD display becomes increasingly blurred. In addition, due to the low design installation height of the display, operators need to squat repeatedly to observe and confirm the readings during the inspection process. These two problems make it difficult for inspectors to easily confirm the valve opening status, which may affect the adjustment accuracy of the equipment.

[0006] Therefore, how to provide an outdoor sleeve mud valve waterproof design that can effectively alleviate water accumulation inside the valve body while improving equipment fault monitoring and early warning capabilities, reducing the frequency of subsequent maintenance, and ensuring long-term stable operation of the system is a technical problem that the present invention urgently needs to solve. Summary of the invention

[0013] The waterproof and alarm structure of the outdoor sleeve mud valve provided by the present invention may also have the following features: the temperature and humidity sensor and the alarm element are arranged on the inner wall of the cavity of the valve body and close to the electrical control main board.

[0014] The waterproof and alarm structure of the outdoor sleeve mud valve provided by the present invention may also have the following feature: when the humidity in the valve body is greater than 90%±5% or when the dew point temperature in the valve body is greater than the ambient temperature, the alarm element alarms.

[0015] The waterproof and alarm structure of the outdoor sleeve mud valve provided by the present invention may also have the following characteristics: the calculation formula of the dew point temperature is:

[0016] Tdew=A*T+B

[0017] Where Tdew is the dew point temperature, A is the calculation coefficient of the valve body temperature, T is the ambient temperature, and B is the calculation constant.

[0018] The waterproof and alarm structure of the outdoor sleeve mud valve provided by the present invention may also have the following feature: the controller is also externally connected to a control terminal.

[0019] The waterproof and alarm structure of the outdoor sleeve mud valve provided by the present invention may also have the following features: the top of the sleeve is sealed, and the sleeve is a transparent polycarbonate sleeve.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the waterproof and alarm structure of the outdoor sleeve mud valve provided by the present invention, a sleeve and a valve body are included, and the sleeve and the valve body are connected. Among them, a screw rod is arranged in the sleeve, and a valve opening scale is arranged on the surface box. A temperature and humidity sensor, an alarm element and a controller are arranged in the valve body. In addition, a waterproof ring is arranged on the sleeve near the valve body, and the temperature and humidity sensor and the alarm element are electrically connected to the controller respectively.

[0023] In addition, the temperature and humidity sensor and the alarm element are connected to the controller through pins, and the detected data is transmitted through the pins, or the controller's instructions are obtained through the pins. In addition, a resistor is connected in series to the pins connecting the temperature and humidity sensor and the controller, and the setting of the series resistor can prevent the sensor element from being burned out due to excessive current.

[0024] In addition, the temperature and humidity sensor and the alarm element are arranged on the inner wall of the cavity of the valve body and close to the electrical control main board. Through this position setting relationship, it is ensured that the temperature and humidity sensor and the alarm element can obtain more representative and accurate parameter data.

[0025] In addition, when the temperature inside the valve body is greater than a certain threshold or the dew point temperature inside the valve body is greater than the ambient temperature, the alarm element will sound an alarm. The dual monitoring mechanism of humidity and dew point temperature can monitor the internal environment of the equipment more sensitively and accurately, facilitating early warning of the device and timely handling of equipment problems, thereby reducing the risk of equipment failure.

[0026] In addition, in the present invention, the calculation formula of the dew point temperature is related to the ambient temperature and can be adaptively adjusted according to the climatic conditions of different regions, thereby ensuring that the outdoor sleeve mud valve can adapt to various environmental conditions.

[0033] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The outdoor sleeve mud valve is used for regular discharge of sludge during sewage treatment.

[0035] like Figures 1 to 3 As shown, the outdoor sleeve mud valve comprises a sleeve 100 and a valve body 200. The sleeve 100 is installed at the top end of the valve body 200 and is located above the valve body 200.

[0036] The sleeve 100 is a transparent polycarbonate sleeve that is resistant to long-term ultraviolet radiation, and is provided with a screw rod 101. The connection between the bottom end and the valve body 200 is provided with an upper circular groove 102 and a lower circular groove 103, respectively. The lower end of the screw rod 101 passes through the bottom of the lower circular groove 103. A hand wheel 104 is also provided on the upper circular groove 102.

[0037] In addition, a screw plate 105 for connection is provided at a position near the upper circular groove 102 on the sleeve 100 , and a plurality of screw holes 106 are provided on the screw plate 105 .

[0038] 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 adopts a highly elastic silicone waterproof ring, and the outer ring of the waterproof ring 108 fits the inner wall of the upper circular groove 102, and the inner ring fits closely with the groove 107 to ensure the waterproof performance of the place.

[0039] In addition, a valve opening scale 109 is provided on the outer surface of the sleeve 100, and the valve opening scale 109 is provided at the original valve opening observation port on the sleeve 100. By providing the valve opening scale 109, the original valve opening observation port is sealed, and the waterproof performance of the sleeve 100 is further ensured.

[0040] The valve body 200 is externally connected to a motor 201 , and a switching handle 202 is also provided on one side thereof, and the manual rotation or electric rotation of the screw rod 101 in the valve body 200 is switched by the switching handle 202 .

[0041] A cavity is provided in the valve body 200 , in which an open source developable circuit board 210 , an electrical control mainboard 220 , a temperature and humidity sensor 230 , an alarm element 240 and a controller 250 are installed.

[0042] The open source development circuit board 210 is provided with a power interface 211 and a data interface 212. The controller 250 is mounted on the open source development circuit board 210. In addition, the controller 250 is connected with a GND pin 213, a digital output pin 214, a VCC pin 215 and a data input pin 216.

[0043] The power interface 211 is connected to an external power source to provide a stable 5V operating voltage for the open source development circuit board 210;

[0044] The data interface 212 connects the bus standby terminal to the control terminal 217 (computer terminal) in the external control room, and then transmits the temperature and humidity data, dew point temperature data and alarm signal transmitted via the MODBUS communication protocol to the control terminal 217 for reading.

[0045] The GND pin 213 and the digital output pin 214 of the controller 250 are respectively connected to the alarm element 240. The controller 250 transmits the signal to the alarm element 240 through the digital output pin 214, and then the alarm element 240 transmits the signal to the GND pin 213 of the controller 250. In addition, the GND pin 213 of the controller 250 is a signal ground terminal.

[0046] The VCC pin 215 and the data input pin 216 of the controller 250 are respectively connected to the temperature and humidity sensor 230, and the temperature and humidity sensor 230 and the two pins are also connected in series with a resistor 217. 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 circuit power supply voltage terminal of the controller 250.

[0047] In addition, the electrical control mainboard 220 is also installed in the cavity of the valve body 200, and 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 and close to the electrical control mainboard 220 to obtain more accurate parameter data.

[0048] In the above waterproof and alarm structure, the alarm working principle is:

[0049] The temperature and humidity sensor 230 first detects the ambient temperature and humidity data in the valve body 200, converts the measured data into a digital signal and transmits the digital signal to the controller 250;

[0050] The controller 250 then processes the data and outputs the result to the alarm element 240. That is, when the environmental conditions trigger an alarm (humidity is greater than 90% ± 5% or the dew point temperature is greater than the ambient temperature), the digital output pin 214 of the controller 250 transmits a signal to the alarm element 240, and the alarm element 240 transmits a signal to the GND pin 213 of the controller 250, reminding the on-duty personnel to conduct on-site inspection and processing.

[0051] In the above principle, the calculation formula of dew point temperature is:

[0052] Tdew=A*T+B

[0053] Where Tdew is the dew point temperature, A is the calculation coefficient of the valve body temperature, T is the ambient temperature, and B is the calculation constant.

[0054] In addition, in this embodiment, the judgment threshold of humidity data is 90%±5%. In other embodiments, it can be adaptively adjusted according to different environments.

[0055] 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.

[0056] According to the waterproof and alarm structure of the outdoor sleeve mud valve in the above embodiment, it includes a sleeve and a valve body, and the sleeve and the valve body are connected. Among them, a screw rod is arranged in the sleeve, and a valve opening scale is arranged on the surface box. A temperature and humidity sensor, an alarm element and a controller are arranged in the valve body. In addition, a waterproof ring is arranged on the sleeve near the valve body, and the temperature and humidity sensor and the alarm element are electrically connected to the controller respectively. Based on the waterproof and alarm structure of the sleeve mud valve, a waterproof ring is arranged on the sleeve to give the mud valve a certain waterproof effect, and a valve opening scale is arranged outside the sleeve surface, and the opening scale can intuitively display the percentage indication of the valve opening. Not only that, the mud valve can also detect the temperature and humidity in the valve body through the temperature and humidity sensor, and then through the calculation and control of the controller, when the temperature and humidity in the valve body exceeds a certain threshold, an alarm is issued through the alarm element, thereby improving the fault detection and early warning capabilities of the entire device, providing more convenience for the inspection of the mud valve, while reducing the frequency of later maintenance, and ensuring the long-term stable operation of the mud valve.

[0057] In addition, a screw plate is provided near the bottom of the sleeve, a groove is provided at the lower part of the screw plate, a waterproof ring is provided in the groove, and the inner wall of the waterproof ring is tightly fitted with the groove, thereby ensuring the waterproofness of the sleeve by the waterproof ring.

[0058] In addition, the temperature and humidity sensor and the alarm element are connected to the controller through pins, and the detected data is transmitted through the pins, or the controller's instructions are obtained through the pins. In addition, a resistor is connected in series to the pins connecting the temperature and humidity sensor and the controller, and the setting of the series resistor can prevent the sensor element from being burned out due to excessive current.

[0059] In addition, the temperature and humidity sensor and the alarm element are arranged on the inner wall of the cavity of the valve body and close to the electrical control main board. Through this position setting relationship, it is ensured that the temperature and humidity sensor and the alarm element can obtain more representative and accurate parameter data.

[0060] In addition, when the temperature inside the valve body is greater than a certain threshold or the dew point temperature inside the valve body is greater than the ambient temperature, the alarm element will sound an alarm. The dual monitoring mechanism of humidity and dew point temperature can monitor the internal environment of the equipment more sensitively and accurately, facilitating early warning of the device and timely handling of equipment problems, thereby reducing the risk of equipment failure.

[0061] In addition, in the present invention, the calculation formula of the dew point temperature is related to the ambient temperature and can be adaptively adjusted according to the climatic conditions of different regions, thereby ensuring that the outdoor sleeve mud valve can adapt to various environmental conditions.

[0062] In addition, the controller is also connected to an external control terminal, through which the detection frequency of the temperature and humidity sensor and the alarm of the alarm element can be controlled and turned on and off.

[0063] In addition, since a valve opening scale is provided on the surface of the sleeve, the original valve opening observation port at the top of the sleeve is sealed, so that the position easy for water to enter is effectively sealed, thereby enhancing the overall waterproof performance of the mud discharge valve and ensuring long-term dryness inside the valve body.
