[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] like Figure 1-Figure 3As shown, a safety protection device for a temperature control system includes a shell 1, a temperature control panel 2 is fixedly arranged inside the shell 1, an electronic component for monitoring the mining environment of a mine is arranged inside the temperature control panel 2, a ventilation pipe 5 is fixedly arranged on one side of the shell 1, an entrance 9 is opened on the other side of the shell 1, a door panel 12 is movably hinged on one side of the entrance 9, and the door panel 12 is generally in a closed state. The device also includes a pad 11, a dustproof cloth 10, a dust collecting chamber 3, a refrigeration chamber 6 and an operating chamber 15, the pad 11 is movably hinged at the bottom of the entrance 9 and is located on the side of the door panel 12 close to the temperature control panel 2, and the dustproof cloth 10 is fixedly connected to the bottom of the entrance 9. The top of the entrance 9 is used to reduce the impact of external dust on the inside of the shell 1 when the staff enters the entrance 9; the refrigeration chamber 6, the operation chamber 15 and the dust collection chamber 3 are arranged in sequence inside the shell 1 from top to bottom, one end of the ventilation pipe 5 is fixedly connected to the dust collection chamber 3, and the other end is fixedly connected to the refrigeration chamber 6. A refrigeration component 7 is installed inside the refrigeration chamber 6, and a thermoelectric cooler is installed on one side of the refrigeration chamber 6. The low-temperature end of the thermoelectric cooler penetrates into the refrigeration chamber 6 and is connected to the inside of the refrigeration component 7 to cool the circulating gas. A fan 18 is fixedly arranged on the bottom of the refrigeration chamber 6 through a horizontally arranged plate, and the fan 18 is responsible for driving To circulate the internal airflow, a dehumidification filling box 8 is fixedly connected to the bottom of the refrigeration chamber 6. The dehumidification filling box 8 is filled with lime. The lime has a dehumidification effect and helps to dry the internal air. The fan 18 pushes the air inside the shell 1 from the operating chamber 15 into the dust collecting chamber 3, and enters the refrigeration chamber 6 through the ventilation pipe 5. The refrigeration component 7 inside the refrigeration chamber 6 cools the air and discharges the air to the operating chamber 15 again. The above operation is then repeated. At the same time, the door panel 12 is generally in a closed state, thereby ensuring that the shell 1 is generally in a sealed state, reducing the influence of external air on the internal electronic equipment, and achieving the purpose of dust prevention. The wet filling box 8 is mainly responsible for reducing the humidity of the internal environment of the shell 1 and maintaining the working environment of important electronic equipment in the temperature control system. After the staff opens the door panel 12 and enters the operating chamber 15, they will first push down the pad 11 located behind the door panel 12, so that the pad 11 is placed on the bottom of the operating chamber 15, and then stand on the pad 11 to operate the temperature control panel 2, so as to prevent the staff who enter from falling into the dust collection chamber 3. When the staff leaves, the pad 11 is restored, so that the dust contaminated by the pad 11 is sandwiched between the pad 11 and the door panel 12, thereby reducing the impact of the dust at this position on the internal environment of the shell 1.
[0022] In some specific implementation schemes, in order to realize automatic storage of the pad 11, an elastic rope 17 is fixedly connected to the upper end of the pad 11, and the end of the elastic rope 17 away from the pad 11 is fixedly connected to the top of the shell 1; after the staff enters the operation chamber 15, they will push down the pad 11. After the operation is completed, the staff leaves the pad 11, and the pad 11 will be restored to its position under the drag of the elastic rope 17, making the pad 11 more flexible and convenient during use.
[0023] In some specific embodiments, in order to reduce the impact of dust on the pad 11 on the internal environment of the operating chamber 15, a fluff pad 13 is fixedly connected to the upper end of the pad 11 near the door panel 12. The fluff pad 13 is strip-shaped and is arranged at the edge of the pad 11; when the pad 11 is restored to a vertical state, there will inevitably be a gap between the pad 11 and the door panel 12, and the internal circulating airflow will enter the gap between the pad 11 and the door panel 12, blowing up the dust stuck on the pad 11. The fluff pad 13 can block the internal circulating airflow from entering between the pad 11 and the door panel 12, reducing the possibility of the circulating airflow bringing the dust on the pad 11 to the operating chamber 15.
[0024] In some specific implementation schemes, in order to improve the bearing strength of the pad 11, multiple groups of parallel arranged support screws 14 are fixedly connected between the dust collecting chamber 3 and the operating chamber 15; the operator's weight is supported by the pad 11, and after the pad 11 is placed on the bottom of the operating chamber 15, the middle of the bottom of the pad 11 is suspended, and the support screws 14 are responsible for supporting the suspended position of the bottom of the pad 11, thereby improving the bearing strength of the pad 11.
[0025] In some specific implementation schemes, in order to facilitate the maintenance of the dust collecting chamber 3, a filter plate 4 is fixedly provided at the connection position between the dust collecting chamber 3 and the ventilation pipe 5, and the air inside the shell 1 enters the dust collecting chamber 3 from the operating chamber 15. Under the action of the filter plate 4, the air and dust are separated, and a dust exhaust port 16 is opened at the bottom of the dust collecting chamber 3, and a sealing plug for blocking the dust exhaust port 16 is fixedly provided on the dust exhaust port 16, and the sealing plug is threadedly connected to the dust exhaust port 16 through bolts; the dust is separated from the airflow under the action of the filter plate 4, and the smaller dust will stick to the filter plate 4, while the larger dust will fall near the dust exhaust port 16. By opening the dust exhaust port 16 at the bottom of the dust collecting chamber 3, the dust near the dust exhaust port 16 can be taken out, thereby avoiding dust accumulation and affecting the filter plate 4.
[0026] In some specific implementation schemes, in order to improve the dust-proof effect, the wall of the outer shell 1 close to the temperature control control panel 2 is thicker, and the temperature control control panel 2 is embedded in the inner plate of the outer shell 1; the temperature control control panel 2 is embedded in the side panel, so that the cold air output by the refrigeration component 7 can directly enter the dust collecting chamber 3 from top to bottom, thereby forming an air wall in front of the temperature control panel 2. While reducing the air circulation resistance inside the outer shell 1, it can also reduce the probability of the temperature control panel 2 being contaminated with dust, thereby improving the protection strength.
[0027] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:
[0028] After the staff opens the door panel 12 and enters the operating chamber 15, they will first push down the pad 11 behind the door panel 12, so that the pad 11 is placed on the bottom of the operating chamber 15, and then stand on the pad 11 to operate the temperature control panel 2. When leaving, the pad 11 will be restored so that the dust on the pad 11 is sandwiched between the pad 11 and the door panel 12, reducing the impact of the dust at this position on the internal environment of the shell 1. The inside of the shell 1 is connected to the ventilation pipe 5, and the fan 18 pushes the air inside the shell 1 from the operating chamber 15 into the dust collection chamber 3, and then enters the refrigeration chamber 6 through the ventilation pipe 5. The low-temperature end of the thermoelectric cooler inside the refrigeration component 7 cools the air and discharges the air to the operating chamber 15 again, and then the above operation is repeated. At the same time, the door panel 12 is generally closed, so as to ensure that the shell 1 is generally sealed, reduce the impact of external air on the internal electronic equipment, and achieve the purpose of dust reduction. The dehumidification filling box 8 is mainly responsible for reducing the humidity of the internal environment of the shell 1 and maintaining the working environment of important electronic equipment in the temperature control system;
[0029] When the pad 11 is restored to a vertical state, there is inevitably a gap between the pad 11 and the door panel 12. The internal circulating airflow will enter the gap between the pad 11 and the door panel 12, blowing up the dust stuck on the pad 11. The fluff pad 13 can block the internal circulating airflow from entering between the pad 11 and the door panel 12, reducing the possibility of the circulating airflow bringing the dust on the pad 11 to the operating chamber 15. The dust is separated from the airflow under the action of the filter plate 4, wherein the smaller dust will stick to the filter plate 4, while the larger dust will fall near the dust outlet 16. By opening the dust outlet 16 at the bottom of the dust collecting chamber 3, the dust near the dust outlet 16 can be removed, thereby avoiding dust accumulation and affecting the filter plate 4. After entering the operating chamber 15, the staff will push down the pad 11. After the operation is completed, the staff will leave the pad 11, and the pad 11 will be dragged by the elastic rope 17 to restore its position, making the pad 11 more flexible and convenient during use.
[0030] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
