[0040] like Figures 1 to 6 As shown, this utility model provides an anti-static grounding resistance monitoring device, including a fixing frame 1, a placement component 2, a resistance monitoring body 3, and a protective component 4. The placement component 2 is height-adjustable and is mounted on one side of the fixing frame 1; the resistance monitoring body 3 is placed on the placement component 2. The resistance monitoring body 3 belongs to mature technology in related fields and can be an intelligent online monitoring instrument for anti-static grounding resistance. The resistance monitoring body 3 is communicatively connected to the software part, which is an online monitoring system for lightning protection grounding resistance in chemical plants. It is used to monitor the resistance value status and grounding connection status of grounding resistance in real time, ensuring the discharge needs of lightning strikes and electromagnetic induction. When the grounding grid or resistance value malfunctions or changes, it can automatically alarm and upload abnormal data to the monitoring backend, facilitating backend personnel to make emergency solutions and rectification measures. In this embodiment, the placement component 2 is a flat plate, which has a simple structure and is easy to process.

[0041] The protective component 4 includes a protective cover 41 and at least one limiting member 42. The protective cover 41 is hinged to the placement member 2. The protective cover 41 has an open position and a closed position. When the protective cover 41 is in the open position, the protective cover 41 is located between the fixing frame 1 and the resistance monitoring body 3 and can abut against the fixing frame 1. When the protective cover 41 is in the closed position, the protective cover 41 and the placement member 2 enclose a closed space, and the resistance monitoring body 3 is located in the closed space. The limiting member 42 is connected to the inner wall of the protective cover 41 and can elastically abut against the outer wall of the resistance monitoring body 3.

[0042] The protective cover 41 is hinged to the placement member 2, and the resistance monitoring body 3 is placed on the placement member 2. After the protective cover 41 is closed, the protective cover 41 and the placement member 2 form a closed space, and the resistance monitoring body 3 is located in the closed space, which can protect the resistance monitoring body 3 and reduce the contact between the air in the chemical plant and the resistance monitoring body 3, thereby reducing the degree of corrosion of the resistance monitoring body 3 and thus improving its service life. A limiting member 42 is provided on the inner wall of the protective cover 41. The limiting member 42 can elastically abut against the outer wall of the resistance monitoring body 3, which can limit the resistance monitoring body 3, prevent the resistance monitoring body 3 from shifting during operation, and also facilitate the opening and closing of the protective cover 41. When the protective cover 41 is in the open position, the protective cover 41 is located between the fixing frame 1 and the resistance monitoring body 3, and can abut against the fixing frame 1. The fixing frame 1 supports the protective cover 41 and saves the space occupied by the protective cover 41 when it is in the open position.

[0043] In addition, since the resistance monitoring body 3 is equipped with a grounding cable 31, which includes E, P and C leads, it can be connected to three external grounding electrode cables. The three grounding electrode cables are buried underground respectively. The placement piece 2 is set on one side of the fixing frame 1 with adjustable height, which makes it convenient to adjust the height of the resistance monitoring body 3 after installation, so that the height of the grounding cable 31 is adapted to the height of the upper end of the three grounding electrode cables, effectively improving the convenience of wiring operations.

[0044] In this embodiment, as Figure 3 As shown, two lugs 11 are fixed on both sides of the fixing frame 1. The lugs 11 are provided with mounting holes 111. By setting the lugs 11 and the mounting holes 111, it is convenient for operators to fix the fixing frame 1 in the production workshop or warehouse of the chemical plant.

[0045] Optionally, in this embodiment, limiting members 42 are connected to the top and side surfaces of the inner wall of the protective cover 41. The limiting member 42 connected to the top surface of the inner wall of the protective cover 41 can elastically abut against the top surface of the resistance monitoring body 3, and the limiting member 42 connected to the side surface of the inner wall of the protective cover 41 can elastically abut against the side surface of the resistance monitoring body 3. When the protective cover 41 is in the closed position, the limiting member 42 connected to the top surface of the inner wall of the protective cover 41 can vertically press the resistance monitoring body 3, and the limiting member 42 connected to the side surface of the inner wall of the protective cover 41 can horizontally press the resistance monitoring body 3, thereby achieving limiting of the resistance monitoring body 3 in various directions, improving the positional accuracy, realizing the stable placement of the resistance monitoring body 3 on the placement member 2, and relatively fixing the resistance monitoring body 3 on the placement member 2. In this embodiment, the limiting member 42 connected to the top surface of the inner wall of the protective cover 41 is a flat plate, and the limiting member 42 connected to the side surface of the inner wall of the protective cover 41 is an arc-shaped plate.

[0046] Optionally, in this embodiment, as Figure 1, Figure 5 and Figure 6 As shown, the protective component 4 also includes an elastic element 43. Both ends of the elastic element 43 are fixedly connected to the inner wall of the protective cover 41 and the limiting element 42, respectively. The limiting element 42 can abut against the outer wall of the resistance monitoring body 3. By providing the elastic element 43, the protective cover 41 can be easily inserted into the resistance monitoring body 3, allowing for flexible opening and closing of the protective cover 41. Specifically, the elastic element 43 is a Z-shaped spring or a spring-loaded spring. In other embodiments, the limiting element 42 is made of an elastic material. One end of the limiting element 42 is fixedly connected to the inner wall of the protective cover 41, and the other end of the limiting element 42 can abut against the outer wall of the resistance monitoring body 3. Specifically, the elastic material can be rubber.

[0047] Optionally, such as Figure 4 and Figure 5 As shown, the placement component 2 is provided with two supports 21 spaced apart. A rotating shaft 44 is fixed to one end of the protective cover 41, and both ends of the rotating shaft 44 are rotatably connected to the two supports 21 respectively. A first rotating handle 45 is fixed to the rotating shaft 44. By setting the rotating shaft 44, the protective cover 41 can be flipped open or closed with the axis of the rotating shaft 44 as the rotation center. By setting the first rotating handle 45, it is convenient for operators to rotate the protective cover 41, reducing the range of motion required when opening the protective cover 41. Specifically, in this embodiment, the rotating shaft 44 is fixed through and fixed to the protective cover 41. This arrangement facilitates the protection of the rotating shaft 44. Both ends of the rotating shaft 44 are rotatably connected to the two supports 21 respectively. A first rotating handle 45 is fixed to the end face of one end of the rotating shaft 44, and the first rotating handle 45 has an S-shaped structure. This arrangement facilitates the rotation of the protective cover 41. In other embodiments, the rotating shaft 44 is located outside the protective cover 41 and fixed to the outer wall of the protective cover 41. Alternatively, both sides of the protective cover 41 are fixed with rotating shafts 44, and the two rotating shafts 44 are rotatably connected to the two supports 21 respectively, and a first rotating handle 45 is fixed on one of the rotating shafts 44.

[0048] Furthermore, in this embodiment, as Figure 2 As shown, a counterweight 411 is fixedly connected to the top surface of the outer wall of the protective cover 41. Specifically, the counterweight 411 is a counterweight block. By setting the counterweight 411, the stability of the protective cover 41 after it is closed can be improved.

[0049] Optionally, such as Figure 1 and Figure 4As shown, the placement component 2 is fitted with a sleeve 23, through which the grounding cable 31 of the resistance monitoring body 3 can pass. The sleeve 23 serves to limit and protect the grounding cable 31. After placing the resistance monitoring body 3 on the placement component 2, passing the grounding cable 31 through the sleeve 23 also facilitates subsequent external wiring. Alternatively, a through-hole can be directly provided on the placement component 2, through which the grounding cable 31 of the resistance monitoring body 3 passes and connects to the external grounding electrode cable.

[0050] Optionally, the protective component 4 also includes a rubber ring 46, which is fixed to the surface of the opening of the protective cover 41. When the protective cover 41 is in the closed position, the rubber ring 46 can contact the top surface of the placement component 2. When the protective cover 41 is closed, the rubber ring 46 can contact the top surface of the placement component 2, which can act as a buffer and prevent damage to the top surface of the placement component 2, while also providing a certain degree of sealing.

[0051] Optionally, the placement component 2 is provided with at least one heat dissipation hole 22, which communicates with the enclosed space. This arrangement allows the heat generated by the resistance monitoring body 3 during operation to be dissipated through the heat dissipation hole 22 when the resistance monitoring body 3 is fixed to the placement component 2. In this embodiment, two sets of heat dissipation holes 22 are provided, located on both sides of the resistance monitoring body 3. In each set, multiple heat dissipation holes 22 are evenly distributed along the length of the placement component 2. This arrangement facilitates manufacturing and provides better heat dissipation.

[0052] Optionally, such as Figure 2 As shown, the anti-static grounding resistance monitoring device also includes an adjustment component 5, which includes a lead screw 51 and a movable base 52. The lead screw 51 is rotatably connected to the fixed frame 1, and the movable base 52 is threadedly connected to the lead screw 51. The placement component 2 is fixed to the movable base 52. The lead screw 51 is used to drive the movable base 52 to move along the length of the lead screw 51, and the placement component 2 is fixed to the movable base 52, thereby adjusting the height of the resistance monitoring body 3. Using the lead screw 51 saves space while providing a large range of height adjustment for the resistance monitoring body 3.

[0053] Optionally, in this embodiment, to save costs, the adjusting assembly 5 further includes a second rotating handle 53. One end of the lead screw 51 passes through the fixed frame 1 and is located outside the fixed frame 1, and is fixedly connected to the second rotating handle 53. By providing the second rotating handle 53, it is convenient for the operator to rotate the lead screw 51. Specifically, the second rotating handle 53 is a strip rod, which is vertically arranged on the lead screw 51 and located at the lower end of the lead screw 51. The structure is simple and convenient for the operator to apply force. In addition, a cylinder or an electric actuator can also be used for adjustment.

[0054] Optionally, the lead screw 51 extends vertically and is mounted on the fixed frame 1. The adjusting assembly 5 also includes at least one guide member 54, both ends of which are fixed to the fixed frame 1 and are arranged parallel to the lead screw 51. The movable seat 52 is slidably connected to the guide member 54. By providing the guide member 54, the vertical movement of the movable seat 52 is guided, making the movement of the movable seat 52 smoother. In this embodiment, two guide members 54 are provided, and they are guide rods. The movable seat 52 is slidably connected to both guide rods.

[0055] In this embodiment, the fixing frame 1 has a rectangular structure and a rectangular inner cavity. The movable seat 52 and the guide member 54 are both located in the rectangular inner cavity, and part of the lead screw 51 is located in the rectangular inner cavity. This arrangement facilitates the processing of the fixing frame 1 and provides high structural strength.

[0056] The working process of the anti-static grounding resistance monitoring device provided in this embodiment is as follows: When the resistance monitoring body 3 needs to be installed in the workshop or warehouse of a chemical plant, the operator first passes the bolt through the mounting hole 111 to fix the fixing frame 1 to the wall of the workshop or warehouse. Then, the resistance monitoring body 3 is placed on the upper surface of the placement plate, and the grounding cable 31 is passed through the sleeve 23. Then, the first rotating handle 45 is manually rotated to make the protective cover 41 rotate downward around the axis of the rotating shaft 44, so that the protective cover 41 covers the resistance monitoring body 3. During the process of the protective cover 41 rotating and closing, the two limiting members 42 gradually contact the top surface of the resistance monitoring body 3, and the four limiting members 42 limit the two sides of the resistance monitoring body 3, so that the resistance monitoring body 3 is limited to the top surface of the placement piece 2, thereby conveniently realizing the protection of the installed resistance monitoring body 3, reducing the contact degree between the air in the chemical plant and the resistance monitoring body 3, thereby reducing the corrosion degree of the resistance monitoring body 3, and thus improving the service life of the resistance monitoring body 3.

[0057] Subsequently, the operator manually rotates the second rotating handle 53 according to the height of the three external grounding electrode cables. The second rotating handle 53 causes the lead screw 51 to rotate, and the lead screw 51 drives the moving seat 52 to rise and fall vertically. The moving seat 52, through the placement piece 2, causes the resistance monitoring body 3 to rise and fall synchronously, so that the height of the grounding cable 31 is adapted to the height of the upper end of the three grounding electrode cables, which is used by the operator for wiring. This facilitates the height adjustment of the resistance monitoring body 3 after installation, and thus effectively improves the convenience of wiring operations for the resistance monitoring body 3.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
