Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of line detection, and in particular to a near electric detection device. BACKGROUND

[0002] The near electric detection device is a safety detection tool for detecting the electric field intensity around the electrical equipment, so as to determine whether to approach the live body. Its main function is to prevent electric shock accidents caused by accidental approach to live equipment, and to protect personnel safety.

[0003] A near electric detection device is often arranged on the mechanical arm of the excavator, so as to prevent the mechanical arm of the excavator from touching the electric wire during the working process / walking process. Since the working environment of the excavator is relatively harsh, and the collision often occurs, the sealing between the shell cover is particularly important. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the present application is to provide a near electric detection device, so as to improve the sealing effect of the near electric detection device.

[0005] The near electric detection device provided by the present application adopts the following technical scheme: comprising a shell, a cover, and a sealing assembly;

[0006] The shell is provided with a mounting groove for mounting the sealing assembly, the mounting groove is arranged in a closed loop around the shell, the sealing assembly protrudes from the mounting groove, and the shell is provided with a protrusion inserted into the cover.

[0007] The cover is provided with a recess matched with the protrusion.

[0008] By adopting the above technical scheme, the shell is provided with a mounting groove arranged in a closed loop around the shell for mounting the sealing assembly. This closed loop design helps to form a continuous sealing defense line in all directions. The sealing assembly protrudes from the mounting groove, which can better contact the cover to achieve sealing and prevent rainwater, dust and the like from entering the gap between the shell and the cover. The shell is provided with a protrusion inserted into the cover, which not only helps to position the shell and the cover during installation, but also enhances the tightness of the connection between the two, reducing the possibility of loosening caused by external forces such as strong winds.

[0009] Optionally, the cover is provided with a plurality of first grooves, and the sealing assembly can extend into the first grooves when the sealing assembly deforms.

[0010] By adopting the above technical scheme, the design of the sealing assembly being higher than the mounting groove makes the sealing assembly inevitably deformed by extrusion when the cover and the shell are closed. This deformation is a key step to achieve good sealing; when the sealing assembly fills into the first groove, it can better fill the possible small gap between the cover and the shell. Originally, the sealing may only rely on the planar contact between the sealing assembly and the cover or the shell for sealing, and now a more complex three-dimensional sealing structure is formed by filling the first groove; the deformation of the sealing assembly changes the contact area and pressure between the sealing assembly and the cover. In the process of filling the first groove, the fit between the sealing assembly and the cover is more closely and complex, and the interaction force between the two is increased, thereby generating greater friction; in harsh outdoor environments, such as windy weather, the line microfilm may be subjected to lateral force or vibration. If the cover is offset, the sealing structure may be damaged, and even the normal work of the internal elements of the equipment may be affected. The enhanced friction can effectively resist these external forces, ensure that the cover remains in a stable position on the shell, maintain the integrity of the sealing structure, and further protect the stable operation of the line microfilm in harsh environments.

[0011] Optionally, the cover is provided with a slope, and the slope is connected with one side of the recess. When the sealing assembly deforms, the sealing assembly abuts against the slope.

[0012] By adopting the above technical scheme, when the sealing assembly deforms due to the closure of the cover and the shell, the slope provides a specific guide direction for the deformation of the sealing assembly. The sealing assembly abuts against the slope, so that it can stretch and deform along the direction specified by the slope when it is extruded. This guidance helps to more reasonably distribute the deformation of the sealing assembly and avoid its disordered expansion or excessive extrusion in a local part; the presence of the slope increases the contact mode and area between the sealing assembly and the cover. Compared with simple planar contact, the abutment of the slope and the sealing assembly forms a more closely and closely sealed structure; when the sealing assembly abuts against the slope, the pressure it bears from the closure of the cover can be dispersed along the slope. This reduces the problem of stress concentration locally borne by the sealing assembly and reduces the risk of damage or sealing failure of the sealing assembly due to excessive local stress;

[0013] Optionally, the shell is provided with a connecting portion, and the reinforcing member is bolted with the connecting portion.

[0014] By adopting the above technical scheme, in order to facilitate the machining of the shell, the complex reinforcing structure is omitted, the reinforcing member is separately machined, and then installed on the shell.

[0015] Optionally, the shell is provided with a circuit board, a clamping assembly clamping the circuit board, and a pop-up assembly popping up the circuit board, the clamping assembly is used to fix the position of the circuit board in the shell, and when the clamping assembly releases the restriction on the circuit board, the pop-up assembly pops up the circuit board for convenient clamping.

[0016] By adopting the above technical solutions, when the circuit board needs to be maintained, repaired or replaced, the ejecting assembly can automatically eject the circuit board after the clamping assembly releases the restriction on the circuit board. This design greatly facilitates the clamping operation of the operator. In a complex working environment, such as maintenance of the high-voltage power near-electricity detection equipment in the field, this convenient clamping mode can save time and effort, reduce the risk of damage to the circuit board or other equipment components due to difficult operation, and improve the efficiency and convenience of equipment maintenance; the clamping assembly and the ejecting assembly work cooperatively to enable the circuit board to be stable during normal operation and to be conveniently taken out and installed when maintenance is needed. This design fully considers the use and maintenance requirements of the equipment in the entire life cycle, improves the maintainability of the equipment, reduces the possibility of long-term shutdown of the equipment due to difficult maintenance, and helps to ensure the reliability and stability of the high-voltage power near-electricity detection equipment during long-term use.

[0017] Optionally, the ejecting assembly comprises a first column fixedly connected to the shell, a first block slidingly connected to the first column, and a first spring sleeved on the first column, the first column penetrates through the circuit board, the circuit board abuts against the first block, and the first spring forces the first block to move upward.

[0018] By adopting the above technical solutions, the first column is fixedly connected to the shell, providing a stable structural basis for the ejecting assembly. It penetrates through the circuit board, playing a role in positioning and guiding, so that the circuit board has a certain moving direction during the ejecting process, ensuring the accuracy and stability of the ejecting action; the first block is slidingly connected to the first column, which enables the first block to move flexibly on the first column. When the circuit board is subjected to force from the ejecting assembly, the first block can smoothly move along the first column, transmitting the force to the circuit board and realizing the ejecting action of the circuit board. At the same time, the circuit board abuts against the first block, which ensures that the ejecting force can effectively act on the circuit board; the first spring is sleeved on the first column, which is the power source of the ejecting assembly. When the first spring is in a compressed state, it stores elastic potential energy. When the restriction of the clamping assembly on the circuit board is released, the elastic potential energy stored in the first spring is released, generating a spring force that forces the first block to move upward. Due to the abutting relationship between the first block and the circuit board, the circuit board also moves upward, realizing the ejecting effect.

[0019] Optionally, the clamping assembly comprises a second column fixedly connected to the shell, a second block slidingly connected to the second column, a clamping block fixedly connected to the second block, and a second spring sleeved on the second column, the clamping block can abut against the circuit board, and the second spring forces the second block to move toward the side of the circuit board.

[0020] By adopting the technical scheme, the second column is fixedly connected to the shell, thereby providing stable structural support for the whole clamping assembly. The second column determines the movement direction and position of the second block and the clamping block, thereby ensuring that the clamping action is performed along a specific direction, and ensuring the accuracy and stability of clamping the circuit board; the second block is slidably connected to the second column, which enables the second block to freely move on the second column. This provides a flexible movement mode for the clamping block, so that the clamping block can be adjusted in position according to the installation condition of the circuit board and external force, to effectively clamp the circuit board; the clamping block is fixedly connected to the second block, and is a component that directly contacts the circuit board and clamps the circuit board. The clamping block can abut against the circuit board, and exerts pressure on the circuit board through contact with the surface of the circuit board, to fix the circuit board at a predetermined position in the shell; the second spring is sleeved on the second column, and is a power source for driving the clamping block to clamp the circuit board. When the second spring is in a compressed or stretched state, the elastic force generated by the second spring forces the second block to move towards the side of the circuit board. This design automatically clamps the circuit board by using the elastic property of the spring, without the need for additional complex operations, thereby ensuring the stability of the circuit board during normal operation of the equipment.

[0021] Optionally, the clamping block is provided with a clamping portion and a driving portion. When the circuit board is pressed down, the circuit board first abuts against the driving portion. The driving portion can convert the downward pressing force of the circuit board into a moving force of the clamping block. The clamping portion limits the vertical movement of the circuit board.

[0022] By adopting the technical scheme, when the circuit board is pressed down, the circuit board first abuts against the driving portion, which realizes the conversion of force types. The force for pressing down the circuit board is originally an external force in a vertical downward direction. Through the special structure of the driving portion, the vertical downward driving force can be converted into a moving force of the clamping block. This conversion of force makes the whole clamping process more automatic and efficient. For example, when the circuit board is installed, the operator only needs to place the circuit board into the shell and press it down, without the need for additional operations on the clamping block. The driving portion can automatically sense and utilize the pressing force to adjust the position of the clamping block. The clamping portion and the driving portion work together to effectively clamp the circuit board. During the installation process, the driving portion first responds to the force for pressing down the circuit board, and adjusts the position of the clamping block. Then, the clamping portion plays a role after the clamping block is moved into position, and fixes the circuit board in the vertical direction. During the operation of the equipment, they cooperate with each other to continuously maintain the stable state of the circuit board.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. The mounting groove arranged around the closed loop of the shell is used to install the sealing assembly, thereby forming a continuous sealing line. The sealing line can effectively block rainwater, dust and the like from entering the interior of the equipment through the gaps between the shell and the cover from various directions, thereby protecting the internal components from the invasion of external environmental factors.

[0025] 2, the shell is provided with a circuit board, a clamping assembly and a pop-up assembly. When the circuit board needs to be maintained, repaired or replaced, the pop-up assembly can automatically pop up the circuit board after the clamping assembly releases the restriction on the circuit board, greatly facilitating the clamping operation of the operator. In complex working environments such as the field, this convenient clamping method can save time and effort, reduce the risk of damage to the circuit board or other equipment components due to difficult operation, and improve equipment maintenance efficiency and convenience.

DETAILED DESCRIPTION

[0034] The following will be described in detail in combination with the accompanying drawings. Figure 1 - the drawings Figure 7 The application will be further described in detail.

[0035] The embodiment of the application discloses a near-electricity detection device.

[0036] Embodiment 1, refer to Figures 1-4 ​, including a shell 1, a cover 2, and a sealing assembly 4; the shell 1 is provided with a mounting groove 11 for mounting the sealing assembly 4, the mounting groove 11 is arranged in a closed loop around the shell 1, the sealing assembly 4 protrudes from the mounting groove 11, and the shell 1 is provided with a protrusion 12 for inserting the cover 2; the cover 2 is provided with a recess 21 for matching the protrusion 12. When the cover 2 is closed with the shell 1, the sealing assembly 4 will be extruded due to the protrusion from the mounting groove 11, and this design ensures that the sealing assembly 4 is in close contact with the cover 2, preventing rain, dust and other external factors from entering the equipment through the gap between the shell 1 and the cover 2. The closed-loop mounting groove 11 provides all-round support for the sealing assembly 4, forming a continuous sealing defense line.

[0037] The shell 1 is provided with a reinforcing member 3, and the shell 1 is provided with a connecting portion, and the reinforcing member 3 is connected with the connecting portion through bolts. This design is convenient for the processing of the shell 1, and the reinforcing member 3 is processed separately and then installed on the shell 1, which enhances the structural strength of the shell 1 without increasing the processing complexity of the shell 1. The reinforced shell 1 can better resist external forces such as strong winds and external impacts, effectively preventing the shell 1 from being distorted, bent or damaged due to strong external forces, thereby ensuring the safety and normal operation of the internal components of the equipment.

[0038] Embodiment 2, refer to Figure 5 The cover 2 is provided with a plurality of first grooves 13, and when the sealing assembly 4 is deformed due to extrusion caused by the closure of the cover 2, the sealing assembly 4 can extend into the first grooves 13. This design allows the sealing assembly 4 to better fill the possible small gaps between the cover 2 and the shell 1 during deformation, forming a more complex three-dimensional sealing structure. Compared with the sealing method relying only on planar contact, this design greatly enhances the sealing effect. At the same time, when the sealing assembly 4 fills the first grooves 13, the contact area and pressure between the sealing assembly 4 and the cover 2 increase, generating greater friction. In harsh outdoor environments, such as strong winds, when the equipment is subjected to lateral forces or vibrations, this friction can effectively prevent the cover 2 from shifting, ensuring the integrity of the sealing structure and ensuring the stable operation of the near-electricity detection equipment in harsh conditions.

[0039] Embodiment 3, refer to Figure 6The cover 2 is provided with a slope 14 connected to one side of the recess 21. When the sealing assembly 4 is deformed, the sealing assembly 4 abuts against the slope 14. The slope 14 provides specific directional guidance for the deformation of the sealing assembly 4, so that the sealing assembly 4 can stretch and deform along the slope 14 when being pressed, avoiding disordered expansion or local excessive pressing. The presence of the slope 14 also increases the contact mode and area between the sealing assembly 4 and the cover 2, forming a tighter and more conformal sealing structure. Moreover, when the sealing assembly 4 abuts against the slope 14, the pressure from the closure of the cover 2 can be dispersed along the slope 14, reducing the stress concentration problem of the local bearing of the sealing assembly 4 and reducing the risk of damage or sealing failure of the sealing assembly 4 caused by excessive local stress.

[0040] Embodiment 4, refer to Figure 7 The shell 1 is provided with a circuit board 5, a clamping assembly 7 for clamping the circuit board 5, and a pop-up assembly 6 for popping up the circuit board 5. The clamping assembly 7 is used to fix the accurate position of the circuit board 5 in the shell 1. When maintenance, repair or replacement of the circuit board 5 is needed, after the clamping assembly 7 is released from the restriction of the circuit board 5, the pop-up assembly 6 can pop up the circuit board 5, facilitating the clamping operation of the operator;

[0041] Refer to Figure 7 The pop-up assembly 6 includes a first column 61 fixedly connected to the shell 1, a first block 63 slidingly connected to the first column 61, and a first spring 62 sleeved on the first column 61. The first column 61 penetrates through the circuit board 5, and the circuit board 5 abuts against the first block 63. The first spring 62 stores elastic potential energy when it is in a compressed state. When the clamping assembly 7 is released from the restriction of the circuit board 5, the elastic potential energy stored in the first spring 62 is released, and the resulting elastic force forces the first block 63 to move upward. Due to the abutting relationship between the first block 63 and the circuit board 5, the circuit board 5 also moves upward, realizing the pop-up effect. The first column 61 provides a stable structural basis for the pop-up assembly 6, and its design of penetrating through the circuit board 5 plays a positioning and guiding role, ensuring the accuracy and stability of the pop-up action.

[0042] Refer to Figure 7The clamping assembly 7 includes a second column 71 fixedly connected to the shell 1, a second block 73 slidably connected to the second column 71, a clamping block 74 fixedly connected to the second block 73, and a second spring 72 sleeved on the second column 71. The clamping block 74 can abut against the circuit board 5, and the elastic force generated by the second spring 72 in the compressed or stretched state forces the second block 73 to move towards the side of the circuit board 5. The second column 71 provides stable structural support for the entire clamping assembly 7, determines the movement direction and position of the second block 73 and the clamping block 74, ensures that the clamping action is performed in a specific direction, and ensures the accuracy and stability of clamping the circuit board 5. The sliding connection between the second block 73 and the second column 71 allows the clamping block 74 to flexibly adjust its position according to the installation condition of the circuit board 5 and external force, thereby effectively clamping the circuit board 5. The clamping block 74, as a component directly contacting the circuit board 5, exerts pressure on the circuit board 5 through contact with the surface of the circuit board 5, thereby fixing the circuit board 5 at a predetermined position in the shell 1.

[0043] Reference Figure 7 The clamping block 74 is provided with a clamping portion 742 and a driving portion 741. When the circuit board 5 is pressed down, the circuit board 5 first abuts against the driving portion 741, which can convert the driving force of the circuit board 5 being pressed down into the moving force of the clamping block 74, thereby realizing the conversion of force types and making the entire clamping process more automated and efficient. When installing the circuit board 5, the operator only needs to place the circuit board 5 into the shell 1 and press it down, without the need for additional operation of the clamping block 74. The driving portion 741 can automatically sense and utilize the pressing force to adjust the position of the clamping block 74. Subsequently, the clamping portion 742 restricts the movement of the circuit board 5 in the vertical direction, and cooperates with the driving portion 741 to effectively clamp the circuit board 5. During the operation of the device, they continuously maintain the stable state of the circuit board 5, preventing the circuit board 5 from being displaced due to vibration and the like.

[0044] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered by the protection scope of the present application.
