Description

Technical Field

[0001] This utility model relates to the field of manhole cover technology, and in particular to an environmentally friendly intelligent manhole cover for water supply pipelines in water conservancy projects. Background Technology

[0002] Water pipelines in water conservancy projects generally have large manholes and long laying distances, involving various complex geological conditions, such as earthmoving sections, river crossing sections, and areas rich in groundwater. In order to meet the design requirements of water conservancy projects and to manage important parts such as pipeline valves and flanges in the future, it is necessary to set up a lot of valve manholes in water pipelines.

[0003] Traditional valve wells are made of ductile iron or concrete, making them heavy and inconvenient for daily valve management. Furthermore, in Northeast China, valve wells are frequently plagued by freezing and cracking of valves and pipes due to dampness and low temperatures, or corrosion caused by moisture, severely impacting the stability of local urban water supply. To ensure the safety of drinking water for residents, there is an urgent need to design an environmentally friendly and intelligent well cover to address the problems of freezing damage caused by low temperatures and corrosion caused by dampness within valve wells. Therefore, we propose an environmentally friendly intelligent well cover for water conservancy projects' water transmission pipelines. Utility Model Content

[0004] The main purpose of this utility model is to propose an environmentally friendly intelligent well cover for water supply pipelines in water conservancy projects, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an environmentally friendly intelligent manhole cover for water supply pipelines in water conservancy projects, comprising a soil layer, a water supply pipeline, and a valve well. The water supply pipeline is fixedly installed inside the soil layer, and the valve well is fixedly connected to the water supply pipeline. The valve well is characterized by having an intelligent manhole cover at its top, comprising a sealing base, a rotating shaft, and a power generation cover. A power generation cover has a conductor, and the other end of the conductor has a battery. A first temperature-controlled heating cable is installed on the water supply pipeline, and a second temperature-controlled heating cable is installed on the valve well. A temperature control box is installed at one end of the first temperature-controlled heating cable.

[0006] As a further description of the above technical solution, the sealing base and the power generation cover are rotatably connected by a rotating shaft. The first temperature control heating cable is fixedly spirally wound around the outer wall of the water supply pipeline. A first temperature sensor is fixedly installed inside the water supply pipeline. The second temperature control heating cable is fixedly spirally wound around the outer wall of the valve well. A second temperature sensor is fixedly installed inside the valve well. Both the first temperature sensor and the second temperature sensor are electrically connected to the temperature control box.

[0007] As a further description of the above technical solution, the electrical wire is electrically connected to the storage battery, and the temperature control box is electrically connected to the storage battery, the first temperature control heating cable, and the second temperature control heating cable, respectively.

[0008] As a further description of the above technical solution, the power generation cover includes a lower cover plate, an upper cover plate, and a light-transmitting solar film. The lower cover plate and the upper cover plate are evenly provided with a plurality of threaded holes, and each of the threaded holes is threaded with a fastening bolt.

[0009] As a further description of the above technical solution, the lower cover plate is adapted to the sealing base and is rotatably connected by a rotating shaft. The lower cover plate and the upper cover plate have the same diameter. The light-transmitting solar film is distributed between the lower cover plate and the upper cover plate, and the light-transmitting solar film is electrically connected to the electrical wire.

[0010] As a further description of the above technical solution, both the upper cover plate and the lower cover plate are made of transparent plexiglass.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By setting up a smart manhole cover, electrical wires and storage batteries, solar energy is converted into electrical energy and stored in the storage batteries, effectively utilizing natural resources. Moreover, the power generation cover in the smart manhole cover is transparent, allowing staff to observe the condition inside the valve well without opening the manhole cover, which facilitates daily inspection work.

[0013] 2. By integrating a smart well cover, electrical wires, a storage battery, a first temperature-controlled heating cable, a second temperature-controlled heating cable, a first temperature sensor, a second temperature sensor, and a temperature control box, the system effectively solves the problems of freezing damage caused by low temperatures and corrosion caused by moisture in the valve well, thus extending the lifespan of the equipment inside the valve well. Sunlight directly enters the well, raising the internal temperature while simultaneously generating electricity using a solar film. The transparent solar film in the power generation cover converts solar energy into electrical energy, which is then transmitted through electrical wires to the storage battery. This stored energy powers the first and second temperature-controlled heating cables, the first and second temperature sensors, and the temperature control box. The first and second temperature sensors detect the temperature of the water pipeline and the valve well, respectively, and transmit the signals to the temperature control box. When the temperature falls below the set minimum temperature, the temperature control box compares the set value with the actual temperature and outputs a control signal to adjust the power of the first or second temperature-controlled heating cable to maintain the required temperature and ensure the stable operation of the water pipeline.

[0020] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1-5This utility model provides a technical solution: an environmentally friendly intelligent manhole cover for water supply pipelines in water conservancy projects, comprising a soil layer 1, a water supply pipeline 2, and a valve well 3. The water supply pipeline 2 is fixedly installed inside the soil layer 1, and the valve well 3 is fixedly connected to the water supply pipeline 2. An intelligent manhole cover 4 is installed at the top of the valve well 3. The intelligent manhole cover 4 includes a sealing base 41, a rotating shaft 42, and a power generation cover 43. The sealing base 41 and the power generation cover 43 are rotatably connected through the rotating shaft 42. An electrical wire 5 is electrically connected to the power generation cover 43, and a battery 6 is electrically connected to the end of the electrical wire 5 away from the power generation cover 43. A first temperature-controlled heating cable 7 is fixedly spirally wound on the outer wall of the water supply pipeline 2, and a second temperature-controlled heating cable 9 is fixedly spirally wound on the outer wall of the valve well 3. A first temperature sensor is fixedly installed inside the water supply pipeline 2. The system includes a first temperature sensor installed in the upper part of the water supply pipeline 2 to prevent sediment from covering the sensor. A second temperature sensor is fixedly installed in the valve well 3. Specifically, the second temperature sensor is fixed to the pipe wall with thermally conductive adhesive and sealed with waterproof sealant. The second temperature sensor is installed in the middle section of the valve well 3. The first temperature sensor is used to detect the real-time temperature in the water supply pipeline 2, and the second temperature sensor is used to detect the real-time temperature in the valve well 3. A temperature control box 8 is set at one end of the first temperature-controlled heating cable 7. Both the first and second temperature sensors are electrically connected to the microcontroller in the temperature control box 8. The temperature control box 8 is electrically connected to the battery 6, the first temperature-controlled heating cable 7, and the second temperature-controlled heating cable 9 through a circuit breaker.

[0024] The power generation cover 43 includes a lower cover plate 431, an upper cover plate 432, and a light-transmitting solar film 433. The lower cover plate 431 is adapted to the sealing base 41 and is rotatably connected by a rotating shaft 42. The lower cover plate 431 and the upper cover plate 432 have the same diameter. Both the upper cover plate 432 and the lower cover plate 431 are made of organic glass with a light transmittance of ≥85%. The light-transmitting solar film 433 is distributed between the lower cover plate 431 and the upper cover plate 432. Even without opening the manhole cover, workers can observe the interior of the valve well 3 through the power generation cover 43. In some cases, the light-transmitting solar film 433 is electrically connected to the wire 5 through the photovoltaic controller. The lower cover plate 431 and the upper cover plate 432 are evenly provided with a number of threaded holes 434. The upper cover plate 432 is fixed to the lower cover plate 431 by passing the fastening bolts 435 through the threaded holes 434 on the upper cover plate 432 and the threaded holes 434 on the lower cover plate 431 in sequence. It should be noted that the size of the light-transmitting solar film 433 is smaller than the upper cover plate 432 and the lower cover plate 431 to avoid interfering with the tightening of the fastening bolts 435.

[0025] To further explain, the sealing base 41 and the lower cover plate 431 are sealed by a waterproof rubber sealing ring. Specifically, an annular sealing groove is provided on the top edge of the sealing base 41, and a waterproof rubber sealing ring is embedded in the groove. A sealing flange is provided on the lower edge of the generator cover 43 at the position corresponding to the sealing groove. After the shaft 42 is rotated and closed, the sealing flange and the rubber sealing ring are tightly fitted to form a waterproof sealing structure.

[0026] To further explain, the edges of the light-transmitting solar film 433 can be sealed with the lower cover plate 431 and the upper cover plate 432 by silicone-based sealant to prevent moisture from seeping in; the connection end of the electrical wire 5 to the solar film adopts a waterproof joint, and the joint is wrapped with insulating waterproof tape to ensure the sealing of the electrical connection.

[0027] To further explain, during installation, the battery 6 needs to be protected inside a waterproof protective box. The protective box is made of ABS engineering plastic and the inner wall is coated with an epoxy resin moisture-proof layer. The wires 5 enter the protective box through the waterproof wiring hole and connect to the battery.

[0028] To further explain, the first and second temperature sensors are electrically connected to the microcontroller inside the temperature control box via shielded twisted-pair cables. The communication interface adopts the RS-485 standard, which supports long-distance signal transmission and has strong anti-interference capabilities. The microcontroller presets a temperature threshold (such as a minimum anti-freezing temperature of 5°C), receives sensor data in real time, and compares it with the threshold. When the detected temperature is lower than the set threshold, the microcontroller adjusts the input voltage of the first temperature-controlled heating cable 7 and the second temperature-controlled heating cable 9 to achieve stepless power adjustment.

[0029] It should be noted that both the first and second temperature sensors are platinum resistance temperature sensors (PT100 / PT1000) with anti-electromagnetic interference shielding. This model of temperature sensor has a temperature measurement range of -200℃ to 1300℃ (the standard model can cover the water pipe requirements of -50℃ to 150℃), strong anti-interference, suitable for long-distance transmission, and an IP69K protection rating (fully waterproof design, can be directly immersed in water). It has high mechanical strength, good pressure resistance, and is suitable for buried or exposed pipelines. The first temperature-controlled heating cable 7 and the second temperature-controlled heating cable 9 are both low-temperature self-regulating heating cables (DBR-P / J series). When installing the temperature-controlled heating cable, it needs to be laid spirally along the outer wall of the pipeline, with a fixing spacing of ≤30cm. The outer layer needs to be covered with a waterproof and corrosion-resistant fluoroplastic outer sheath, which can effectively resist the corrosion of chemical substances in water conservancy projects and extend its service life.

[0030] It should be noted that this utility model is an environmentally friendly intelligent manhole cover for water supply pipelines in water conservancy projects. Workers can observe the specific conditions inside the valve well 3 through the transparent power generation cover 43 without opening the manhole cover. During normal operation, sunlight shines directly into the well through the intelligent manhole cover 4, increasing the temperature inside the valve well 3. Simultaneously, the light-transmitting solar film 433 in the power generation cover 43 converts solar energy into electrical energy, which is then transmitted to the battery 6 via the wire 5 for storage. The stored electrical energy powers the operation of the first temperature-controlled heating cable 7, the second temperature-controlled heating cable 9, and the temperature control box 8. The first and second temperature sensors can detect the temperature inside the water supply pipeline 2 and the valve well 3 respectively and transmit the detected signals to the temperature control box 8. When the temperature is lower than the set minimum temperature, the temperature control box 8 compares the set value with the actual temperature value and then outputs a control signal to adjust the power of the first temperature-controlled heating cable 7 or the second temperature-controlled heating cable 9, thereby maintaining the required temperature and ensuring the stable operation of the water supply pipeline. Compared with existing environmentally friendly smart manhole covers for water pipelines in water conservancy projects, this utility model has a simple and lightweight structure. It allows for direct inspection of the valve well without opening the manhole cover. It can convert solar energy into electrical energy and then use a temperature-controlled heating cable for heating, which is energy-saving and environmentally friendly. It solves the problems of freezing damage caused by low temperature and corrosion caused by moisture in the equipment inside the valve well.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
