DETAILED DESCRIPTION
[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention 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 only used to explain the present invention and are not intended to limit the present invention.
[0023] The specific implementation of the present invention is described in detail below with reference to specific embodiments.
[0024] In one embodiment, see Figure 1 and Figure 2 A protective device for concrete temperature monitoring equipment includes a bottom plate 2, a protective shell 1 and a base 3. The protective shell 1 is detachably connected to the bottom plate 2. Ventilation mesh plates 10 are provided on the two oppositely distributed side walls of the protective shell 1. Through holes 6 are provided inside the bottom plate 2 and the base 3. A sealing mechanism 4 is provided inside the through hole 6 inside the bottom plate 2. The sealing mechanism 4 is used to seal the through hole 6 inside the bottom plate 2. A symmetrically distributed telescopic rod 7 is fixed to the top of the base 3. The top of the telescopic rod 7 is fixedly connected to the bottom of the bottom plate 2. A blocking mechanism 5 is provided above the bottom plate 2. When the telescopic rod 7 drives the bottom plate 2 to move upward, the blocking mechanism 5 is used to block the ventilation mesh plate 10.
[0025] In this embodiment, when the protective device is in use, the base 3 is placed or installed on the concrete surface, and the temperature monitoring device is installed on the top of the bottom plate 2. After the temperature monitoring device is installed, the temperature measuring wire on the temperature monitoring device passes through the bottom plate 2 and the through hole 6 inside the base 3. The concrete temperature is sensed by the temperature measuring wire, and the data is fed back to the temperature monitoring device, thereby achieving the purpose of concrete temperature monitoring. After the temperature monitoring device is installed, the protective shell 1 can be installed on the top of the bottom plate 2. After the protective shell 1 is installed, the sealing mechanism 4 inside the through hole 6 inside the bottom plate 2 will automatically seal the gap between the through hole 6 and the temperature measuring wire, effectively improving the sealing performance between the temperature measuring wire and the through hole 6, avoiding rainwater from entering the top of the bottom plate 2 through the through hole 6 in rainy weather, thereby protecting the temperature detector inside the protective shell 1. In addition, a ventilation mesh plate 10 is provided on the side wall of the protective shell 1. When the weather is good, the temperature monitoring device is dissipated by natural ventilation. In order to prevent the temperature monitoring equipment from being overheated, in rainy weather, the telescopic rod 7 drives the bottom plate 2 to move upward, and the bottom plate 2 drives the temperature detection equipment and the protective shell 1 to move upward. On the one hand, it can prevent the protective shell 1 from being soaked in rainwater for a long time. On the other hand, the blocking mechanism 5 automatically blocks the ventilation mesh plate 10, thereby preventing rainwater from penetrating into the protective shell 1 through the ventilation mesh plate 10, further improving the protection effect of the temperature monitoring equipment. That is, the protective device effectively improves the protection performance of the equipment through the detachable protective shell 1, the ventilation mesh plate 10 and the sealing mechanism 4. In good weather, the ventilation mesh plate 10 realizes natural heat dissipation to prevent the equipment from overheating. After the protective shell 1 is installed, the sealing mechanism 4 automatically closes the gap between the through hole 6 and the temperature measuring line, thereby ensuring the sealing performance and preventing rainwater from seeping in. On rainy days, the telescopic rod 7 drives the bottom plate 2 to rise, and at the same time the blocking mechanism 5 blocks the ventilation mesh plate 10, which not only prevents the equipment from being soaked for a long time, but also ensures the dryness and safety of the internal temperature monitoring instrument, and significantly improves the stability and service life of the equipment in harsh environments.
[0026] See also Figure 1-Figure 3 The sealing mechanism 4 includes an inflatable airbag 41 fixedly connected to the inner wall of the through hole 6, the inflatable airbag 41 is connected to a first air pipe 42, and the end of the first air pipe 42 away from the inflatable airbag 41 is connected to an air intake assembly, which is used to inflate the interior of the first air pipe 42; After the temperature monitoring equipment is installed, the protective shell 1 is installed on the top of the base plate 2. During the installation of the protective shell 1, the air intake assembly automatically inflates the first air pipe 42. The gas enters the inflatable airbag 41 through the first air pipe 42, thereby causing the inflatable airbag 41 to expand. After the inflatable airbag 41 expands, it fits tightly with the temperature measuring line, thereby sealing the gap between the through hole 6 and the temperature measuring line, ensuring the sealing performance and avoiding rainwater from entering the top of the base plate 2 through the through hole 6 in rainy weather, thereby causing damage to the temperature monitoring equipment.
[0027] See also Figure 1-Figure 3 The air intake assembly includes a first air pressure cylinder 43 fixedly connected to the top of the bottom plate 2, the first air pressure cylinder 43 is communicated with the first air pipe 42, a first air pressure rod 44 passes through the top of the first air pressure cylinder 43, the first air pressure rod 44 is slidably connected to the inner wall of the first air pressure cylinder 43, a pressure plate 46 is fixed to the top of the first air pressure rod 44, an elastic member 45 is fixed to the bottom of the pressure plate 46, and the lower end of the elastic member 45 is fixedly connected to the top of the first air pressure cylinder 43; When the temperature monitoring equipment is installed, the protective shell 1 can be installed. During the installation process, the protective shell 1 will squeeze the pressure plate 46 through its top, so that the pressure plate 46 drives the first gas pressure rod 44 to move downward. While the first gas pressure rod 44 moves downward, it squeezes the gas inside the first gas pressure cylinder 43. The gas inside the first gas pressure cylinder 43 enters the inflatable airbag 41 through the first air pipe 42, thereby causing the inflatable airbag 41 to expand and fit tightly with the temperature measuring line, ensuring the sealing performance and avoiding rainwater from entering the top of the bottom plate 2 through the through hole 6 in rainy weather, thereby causing damage to the temperature monitoring equipment. The elastic part 45 can be a spring. When the protective shell 1 does not squeeze the pressure plate 46, the elastic part 45 can play a resetting role on the first gas pressure rod 44 through the pressure plate 46, thereby causing the gas inside the inflatable airbag 41 to flow back to the first gas pressure cylinder 43 through the first air pipe 42. The inflatable airbag 41 no longer expands, making it convenient for the staff to pull out the temperature measuring line from the through hole 6, thereby facilitating the staff to disassemble the temperature monitoring equipment.
[0028] See also Figure 1 and Figure 4 The blocking mechanism 5 includes a blocking plate 51 symmetrically arranged above the bottom plate 2. The side wall of the blocking plate 51 is in contact with the inner wall of the protective shell 1. The bottom of the blocking plate 51 is fixed with a symmetrically distributed sliding rod 52. The sliding rod 52 passes through the bottom plate 2 and is slidably connected to the bottom plate 2. The lower end of the sliding rod 52 is fixedly connected to the base 3. When the weather is good, the blocking plate 51 is located above the ventilation mesh plate 10, and the blocking plate 51 does not block the ventilation mesh plate 10. At this time, the temperature monitoring equipment can be cooled by natural ventilation. In rainy weather, the telescopic rod 7 drives the bottom plate 2 to move upward, and the bottom plate 2 drives the temperature detection equipment and the protective shell 1 to move upward until the ventilation mesh plate 10 on the side wall of the protective shell 1 moves to the side of the blocking plate 51. At this time, the blocking plate 51 has a blocking effect on the ventilation mesh plate 10, thereby preventing rainwater from penetrating into the interior of the protective shell 1 through the ventilation mesh plate 10, further improving the protection effect of the temperature monitoring equipment.
[0029] In another embodiment, see Figure 4 and Figure 5 , the side of the blocking plate 51 close to the ventilation mesh plate 10 is provided with a back-blowing component, when the telescopic rod 7 drives the bottom plate 2 to move downward, the back-blowing component is used to back-blow the ventilation mesh plate 10; In this embodiment, when the weather is good again, the bottom plate 2 moves downward through the telescopic rod 7, and the bottom plate 2 drives the protective shell 1 to move downward until the ventilation mesh plate 10 moves below the sealing plate 51. At this time, the temperature monitoring equipment can be cooled by natural ventilation again, and in the process of the ventilation mesh plate 10 moving downward, the backflush component on the side wall of the sealing plate 51 will also backflush the ventilation mesh plate 10, thereby blowing off impurities such as dust adsorbed on the outer wall of the ventilation mesh plate 10, avoiding the influence of impurities on the ventilation effect and ensuring the heat dissipation effect.
[0030] See also Figure 4 and Figure 5 The backflush assembly includes a plurality of air outlet holes 53 provided at the lower end of the side wall of the blocking plate 51. An air cavity 54 is provided inside the blocking plate 51. The air outlet holes 53 are in communication with the air cavity 54. The air cavity 54 is in communication with a second air pipe 55. An end of the second air pipe 55 away from the air cavity 54 is connected to an inflatable component for inflating air into the second air pipe 55. When the weather is good, the bottom plate 2 moves downward through the telescopic rod 7, and the bottom plate 2 drives the protective shell 1 to move downward until the ventilation mesh plate 10 moves to below the blocking plate 51. During the downward movement of the ventilation mesh plate 10, the inflatable component will inflate the inside of the second air pipe 55, and the gas will be discharged from the air outlet 53 through the air cavity 54. As the ventilation mesh plate 10 moves downward, the gas discharged from the air outlet 53 will pass over the surface of the ventilation mesh plate 10, and then have a back-blowing effect on the ventilation mesh plate 10, thereby blowing off impurities such as dust adsorbed on the outer wall of the ventilation mesh plate 10, avoiding the influence of impurities on the ventilation effect and ensuring the heat dissipation effect.
[0031] See also Figure 2 and Figure 5The inflatable component includes a second air pressure cylinder 56 fixedly connected to the top of the bottom plate 2, a piston 57 is slidably connected inside the second air pressure cylinder 56, a second air pressure rod 58 is fixedly connected to the bottom of the piston 57, the second air pressure rod 58 passes through the bottom plate 2 and is slidably connected to the bottom plate 2, and the bottom of the second air pressure rod 58 is fixedly connected to the base 3; In rainy weather, the telescopic rod 7 drives the bottom plate 2 to move upward, and the bottom plate 2 drives the second air pressure cylinder 56 and the protective shell 1 to move upward until the ventilation mesh plate 10 on the side wall of the protective shell 1 moves to the side of the blocking plate 51. During this process, the piston 57 will move downward relative to the second air pressure cylinder 56, and negative pressure will be formed above the piston 57 and inside the second air pressure cylinder 56, thereby extracting external air through the air outlet 53, the air cavity 54 and the second air pipe 55. When the weather is good, the bottom plate 2 moves downward through the telescopic rod 7, and the bottom plate 2 drives the second air pressure cylinder 56 to move downward. At this time, the piston 57 moves upward relative to the second air pressure cylinder 56, thereby squeezing the gas above the piston 57, and the gas inside the second air pressure cylinder 56 enters the air cavity 54 through the second air pipe 55, thereby achieving the purpose of backblowing the ventilation mesh plate 10, where the second air pipe 55 can be a hose.
[0032] See also Figure 1 The side wall of the protective shell 1 is fixed with symmetrically distributed mounting blocks 8, and threaded holes 9 are provided inside the mounting shell and the bottom plate 2; When installing the protective shell 1, align the threaded holes 9 on the mounting shell with the threaded holes 9 inside the base plate 2, and then screw in the bolts to fix the two. This can effectively ensure the stability between the protective shell 1 and the base plate 2. In order to improve the sealing performance between the protective shell 1 and the base plate 2, a sealing gasket can be provided at the bottom of the protective shell 1.
[0033] Working principle: When the protective device is in use, the base 3 is placed or installed on the concrete surface, and the temperature monitoring device is installed on the top of the bottom plate 2. After the temperature monitoring device is installed, the temperature measuring line on the temperature monitoring device passes through the bottom plate 2 and the through hole 6 inside the base 3. The concrete temperature is sensed through the temperature measuring line, and the data is fed back to the temperature monitoring device, thereby achieving the purpose of concrete temperature monitoring. After the temperature monitoring device is installed, the protective shell 1 can be installed on the top of the bottom plate 2. During the installation of the protective shell 1, the protective shell 1 will squeeze the pressure plate 46, so that the pressure plate 46 drives the first gas pressure rod 44 to move downward. The first gas pressure rod 44 squeezes the first gas pressure cylinder while moving downward. The gas inside 43, the gas inside the first air pressure cylinder 43 enters into the inflatable airbag 41 through the first air pipe 42, thereby causing the inflatable airbag 41 to expand and fit tightly with the temperature measuring line, thereby sealing the gap between the through hole 6 and the temperature measuring line, ensuring the sealing performance, and preventing rainwater from entering the top of the bottom plate 2 through the through hole 6 in rainy weather, thereby causing damage to the temperature monitoring equipment. In addition, a ventilation mesh plate 10 is provided on the side wall of the protective shell 1. Under good weather conditions, the temperature monitoring equipment is dissipated by natural ventilation, thereby preventing the temperature monitoring equipment from being overheated. Under rainy weather conditions, the bottom plate 2 is driven upward by the telescopic rod 7, and the bottom plate 2 drives the temperature detection equipment and the protective shell 1 Move upward until the ventilation mesh plate 10 on the side wall of the protective shell 1 moves to the side of the blocking plate 51. On the one hand, it can prevent the protective shell 1 from being soaked in rainwater for a long time. On the other hand, the ventilation mesh plate 10 is blocked by the blocking plate 51, thereby preventing rainwater from penetrating into the protective shell 1 through the ventilation mesh plate 10, further improving the protection effect of the temperature monitoring equipment. When the weather is good again, when the weather is good again, the bottom plate 2 moves downward through the telescopic rod 7, and the bottom plate 2 drives the protective shell 1 to move downward until the ventilation mesh plate 10 moves below the blocking plate 51. In rainy weather, the bottom plate 2 is driven upward by the telescopic rod 7, and the bottom plate 2 drives the second air pressure cylinder 56 and the protective shell 1 to move upward until. The ventilation mesh plate 10 on the side wall of the protective shell 1 moves to the side of the sealing plate 51. During this process, the bottom plate 2 will drive the second air pressure cylinder 56 to move downward. At this time, the piston 57 moves upward relative to the second air pressure cylinder 56, thereby squeezing the gas above the piston 57. The gas inside the second air pressure cylinder 56 enters the air cavity 54 through the second air pipe 55, and the gas is discharged from the air outlet 53 through the air cavity 54. As the ventilation mesh plate 10 moves downward, the gas discharged from the air outlet 53 will pass over the surface of the ventilation mesh plate 10, and then have a back-blowing effect on the ventilation mesh plate 10, thereby blowing off impurities such as dust adsorbed on the outer wall of the ventilation mesh plate 10, avoiding the influence of impurities on the ventilation effect and ensuring the heat dissipation effect.
