Description

Technical Field

[0001] The present application relates to the field of electrical equipment transportation, and in particular to a modular chassis vehicle for electrical cabinets. Background Art

[0002] The chassis vehicle is used to provide precise positioning and transportation for modular installation and movement of electrical cabinet equipment such as high-voltage switchgear and trolley-type switchgear.

[0003] When a general chassis carries the circuit breaker and connects it to the circuit of a trolley switch cabinet, it is difficult to detect the internal environment of the circuit breaker inside the trolley switch cabinet. For example, during operation, if the temperature of the circuit breaker or switch cabinet is too high, the surrounding humidity is too high, resulting in electrical breakdown or leakage, it is difficult to understand the basic conditions of the circuit breaker in the switch cabinet. If a sensor is installed outside the switch cabinet, the external environment is different from the internal environment of the switch cabinet, making it difficult to provide accurate data. Manual detection will be dangerous. Summary of the Invention

[0004] In order to improve the above-mentioned problems, the present application provides a modular chassis vehicle for an electrical cabinet.

[0005] The modular chassis vehicle for electrical cabinets provided in this application adopts the following technical solutions:

[0006] A modular chassis vehicle for an electrical cabinet comprises a static frame and a dynamic frame; a handwheel is provided on the static frame, and a transmission screw and a fixing nut are provided on the dynamic frame, the handwheel is detachably connected to the transmission screw, and the fixing nut is threadedly connected to the transmission screw; it also comprises a telescopic part, an opening and closing part, a first elastic part and a detection component; a telescopic groove is provided inside the transmission screw, and a sliding opening connected to the telescopic groove is provided on the surface of the transmission screw; the telescopic part is located in the telescopic groove, and one end passes through the transmission screw and is detachably connected to the handwheel, and the other end is connected to the first elastic part, and the first elastic part is connected to the inner wall of the telescopic groove; an extension protrusion is provided on the telescopic part, and the extension protrusion extends outward through the sliding opening; an opening and closing part is also sleeved on the transmission screw, and the opening and closing part is connected to the extension protrusion; at least one group of detection components are also provided on the dynamic frames on both sides of the opening and closing part, the detection component abuts against the opening and closing part, and when the telescopic part is pulled by the handwheel, the opening and closing part drives the opening and closing part to open and close the detection component.

[0007] By adopting the above technical solution, when data detection of the switch cabinet or circuit breaker is required, the user pulls the telescopic part through the handwheel, and the telescopic part moves along the telescopic groove. During the movement, the opening and closing part is driven along the sliding opening by the extended protrusion, and the opening and closing part moves and contacts the detection component, thereby opening and closing the detection component. The handwheel can be used to achieve the opening and closing effect of the detection component without touching the switch cabinet or chassis, thereby ensuring the stable and safe acquisition of the detection data in the switch cabinet.

[0008] Optionally, the telescopic member matches the style of the telescopic slot, and a pulling head is provided at one end of the telescopic member located on the static frame, and the pulling head is larger than the notch of the telescopic slot.

[0009] By adopting the above technical solution, the styles are matched so that the telescopic part can fit into the wall of the telescopic groove to reduce the generation of gaps and ensure that the position of the telescopic part will not shift when it moves along the telescopic groove, so that the opening and closing effect of the opening and closing part on the detection component is more stable. The setting of the pulling head can provide a pulling point to facilitate the pulling of the telescopic part.

[0010] Optionally, the transmission screw is divided into three sections, the first section is a threaded section, which is connected to the static frame; the second section is a smooth opening section, with a sliding opening opened to the opening section; the third section is a solid section, which is pivotally connected to the moving frame.

[0011] By adopting the above technical solution, the transmission screw is divided into three sections, each corresponding to a different function. The cooperation between the threaded section and the fixed nut ensures the stable movement of the dynamic frame. The opening section is no longer provided with threads to ensure the stable movement of the opening and closing parts. The solid section ensures gravity balance and at the same time ensures the stability of the pivot connection.

[0012] Optionally, the detection component includes a guide rail, an opening and closing frame, a second elastic member and a first sensor; the guide rail and the first sensor are both arranged on the moving vehicle frame, and the first sensor is located at one end of the guide rail, and the opening and closing member is located at the other end of the guide rail; the opening and closing frame is slidably connected to the guide rail, and one end extends to the opening and closing member and abuts against the opening and closing member, and the other end is spaced a preset distance from the first sensor; a connecting ring is also provided on the guide rail, and the connecting ring is sleeved on the outer wall of the opening and closing frame, one end of the second elastic member is connected to the connecting ring, and the other end is wrapped around the opening and closing frame and connected to the opening and closing frame; the elastic force of the first elastic member is greater than the elastic force of the second elastic member.

[0013] By adopting the above technical solution, when it is necessary to open the detection component, the opening and closing member is pushed by the elastic force of the first elastic member to push the opening and closing frame, and the opening and closing frame overcomes the elastic force of the second elastic member and moves along the guide rail, and abuts against the first sensor switch, thereby opening the first sensor. When it is necessary to close the first sensor, the opening and closing member is driven by the telescopic member to move along the sliding opening, and when it is separated from the opening and closing frame, the opening and closing frame is reset by the elastic force of the second elastic member and separated from the first sensor switch, and the first sensor is closed, thereby opening and closing the first sensor. The opening and closing of the first sensor is used to perform data detection on the chassis and the high-voltage switchgear or circuit breaker.

[0014] Optionally, the motor vehicle frame is further provided with a switching component arranged parallel to the transmission screw, and the switching component abuts against the opening and closing member.

[0015] By adopting the above technical solution, the switching component is used to provide switching when detecting other data, so that the original data detection will not affect the detection of another set of data.

[0016] Optionally, the switching assembly includes a parallel rail, a switching frame, an abutment frame and a second sensor; the parallel rail is installed on the motor vehicle frame, and the switching frame is slidingly connected to the parallel rail; the first sensor and the second sensor are both installed on the switching frame; the abutment frame is connected to the switching frame and abuts against the opening and closing member.

[0017] By adopting the above technical solution, when the telescopic part pulls the opening and closing part to move, the opening and closing part drives the switching frame to move by pushing the abutment frame, so that the first sensor on the switching frame moves, and the second sensor is moved to the corresponding position of the opening and closing frame. At the same time, the opening and closing part synchronously pushes the opening and closing frame, so that the opening and closing frame contacts the switch of the second sensor, thereby turning on the second sensor. The second sensor can adopt a leakage current sensor to detect whether there is leakage in the chassis vehicle and the switch cabinet.

[0018] Optionally, the opening and closing parts are two groups of oppositely arranged conical sleeves, namely a first conical sleeve and a second conical sleeve. The conical surface of the first conical sleeve abuts against the opening and closing frame, and the flat end of the first conical sleeve abuts against the switching assembly; the second conical sleeve and the second sensor are located on the same horizontal straight line, and when the telescopic part moves, the second conical sleeve and the second sensor move synchronously.

[0019] By adopting the above technical solution, the first conical sleeve pushes the opening and closing part to open the first sensor, and the second conical sleeve pushes the opening and closing part to open the second sensor. At the same time, the telescopic part synchronously drives the first conical sleeve and the second conical sleeve to move, thereby ensuring that the two groups of conical sleeves do not interfere with the opening and closing of different sensors.

[0020] Optionally, a separation port is further provided on one side of the first conical sleeve and the second conical sleeve. When any conical sleeve rotates, the separation port is located on the abutment frame or the opening and closing frame, so that the abutment frame or the opening and closing frame passes through the separation port.

[0021] By adopting the above technical solution, when rotating to the opening and closing frame or the abutment frame, the opening and closing frame or the abutment frame can pass through the separation port, so that the conical sleeve is not affected by the opening and closing frame and the abutment frame and continues to move. This method can facilitate the transmission screw to move over the opening and closing frame and the abutment frame, that is, it is convenient to separate the moving frame and the static frame for maintenance or repair.

[0022] Optionally, the dynamic vehicle frame is further provided with an electric drive assembly, which is connected to the transmission screw and provides driving action; the electric drive assembly is also connected to the detection assembly and the switching assembly to provide driving action synchronously.

[0023] By adopting the above technical solution, an electric drive component is set up so that the structure on the chassis can be selectively driven manually or by rotary electric drive. When manually driven, the transmission screw can be driven to rotate by the handwheel when there is no power supply, and the electric drive component can be used for driving when there is power supply. The driving mode can be selected by the user to drive the detection component, the switching component and the separation of the dynamic and static frames.

[0024] Optionally, the electric drive assembly includes a motor, a sprocket group and a drive cylinder; the motor is installed on one side of the moving vehicle frame, and the motor is connected to the transmission screw through a linkage wheel group; the drive cylinder and the transmission screw are arranged parallel to the moving vehicle frame, and the telescopic end is connected to the abutment frame.

[0025] By adopting the above technical solution, the electric drive component can be used to automatically drive the dynamic and static frames to separate, and the driving effect of the opening and closing parts can be used to realize the automatic switching and automatic opening and closing of the sensor.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When data detection of the switch cabinet or circuit breaker is required, the user pulls the telescopic part with the handwheel, and the telescopic part moves along the telescopic slot. During the movement, the opening and closing part is driven along the sliding opening by the extended protrusion. The opening and closing part moves and contacts the detection component, thereby opening and closing the detection component. The handwheel can be used to open and close the detection component without touching the switch cabinet or chassis, ensuring stable and safe acquisition of detection data in the switch cabinet;

[0028] 2. The matching style enables the telescopic part to fit the wall of the telescopic slot to reduce the generation of gaps and ensure that the position of the telescopic part will not shift when it moves along the telescopic slot, making the opening and closing effect of the opening and closing part on the detection component more stable. The setting of the pulling head can provide a pulling point to facilitate the pulling of the telescopic part;

[0029] 3. The transmission screw is divided into three sections, each corresponding to a different function. The threaded section cooperates with the fixing nut to ensure the stable movement of the moving carriage. The opening section is not provided with threads to ensure the stable movement of the opening and closing parts. The solid section ensures gravity balance and the stability of the pivot connection.

[0030] 4. When the detection component needs to be opened, the opening and closing member is pushed by the elastic force of the first elastic member to push the opening and closing frame. The opening and closing frame overcomes the elastic force of the second elastic member and moves along the guide rail, and abuts against the first sensor switch, thereby opening the first sensor. When the first sensor needs to be closed, the opening and closing member is driven by the telescopic member to move along the sliding opening, and when it is separated from the opening and closing frame, the opening and closing frame is reset by the elastic force of the second elastic member and separated from the first sensor switch, and the first sensor is closed, thereby opening and closing the first sensor. The opening and closing of the first sensor is used to perform data detection on the chassis and the high-voltage switchgear or circuit breaker. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following is combined with Figure 1 -Attached Figure 7 , further details of this application are given.

[0045] An embodiment of the present application discloses a modular chassis vehicle for an electrical cabinet.

[0046] A modular chassis vehicle for electrical cabinets, referring to Figure 1 and Figure 2As shown, it includes a static frame 1 and a dynamic frame 2; the static frame 1 and the dynamic frame 2 are separable, a handwheel is provided on the static frame 1, and a transmission screw 21 and a fixing nut are provided on the dynamic frame 2 (the fixing nut in the figure is covered by a cover and is therefore not shown), the handwheel and the transmission screw 21 are detachably connected, and the detachable connection can be a snap connection, one end of the transmission screw 21 can be a hexagonal block structure, and the handwheel can be provided with a hexagonal block groove, so that the handwheel can be plugged into the transmission screw 21, that is, by rotating the transmission screw 21, the fixing nut is screwed to the transmission screw 21, and when the handwheel rotates the fixing nut, it drives the dynamic frame 2 to move along the axial direction of the transmission screw 21, so that the dynamic frame 2 is separated from the static frame 1.

[0047] Among them, a clamping block is also provided on the transmission screw 21, and a clamping frame is also provided on the dynamic frame 2. The clamping frame is provided with a first clamping groove. When the clamping block is located in the first clamping groove, the clamping block is clamped by the first clamping groove and cannot continue to rotate, thereby realizing closing and locking. In addition, a closing and locking rod is also provided on the dynamic frame 2. The closing and locking rod is provided with a second clamping groove. When the clamping block of the transmission screw 21 moves to the second clamping groove, the closing and locking rod can be lowered to make the clamping block clamped in the second clamping groove, so that closing and locking can be performed at another travel point of the transmission screw 21.

[0048] It also includes a telescopic part 3, an opening and closing part 4, a first elastic part 5 and a detection component 6; a telescopic groove 210 is provided inside the transmission screw 21, and a sliding port 22 connected to the telescopic groove 210 is provided on the surface of the transmission screw 21. The telescopic part 3 is located in the telescopic groove 210, and one end passes through the transmission screw 21 and is detachably connected to the handwheel, and the other end is connected to the first elastic part 5. The first elastic part 5 is connected to the inner wall of the telescopic groove 210. The telescopic part 3 can adopt a telescopic rod, and the telescopic rod can move along the telescopic groove 210. The end of the telescopic rod connected to the handwheel can be located outside the telescopic groove 210, so that the handwheel can be engaged with the telescopic rod, and the handwheel can pull the telescopic rod to move. When the handwheel is released, the telescopic rod is reset by the elastic force of the first elastic part 5 and retracted into the telescopic groove 210. The first elastic part 5 can adopt a spring.

[0049] The sliding opening 22 can be opened with at least two, respectively located on both sides of the transmission screw 21, and the telescopic part 3 is provided with an extension protrusion 31, the number of which is consistent with the sliding opening 22, and the extension protrusion 31 corresponds to the sliding opening 22 one by one, and the corresponding extension protrusion 31 extends outward through the sliding opening 22. The extension protrusion 31 has two functions. First, it can provide an installation point for connection, and second, it can provide a limit, that is, determine the moving distance of the telescopic part 3, so that the telescopic part 3 cannot be separated from the sliding opening 22, thereby limiting the moving distance of the telescopic part 3.

[0050] The transmission screw 21 is also provided with an opening and closing member 4, and the opening and closing member 4 is connected to the extension protrusion 31. The opening and closing member 4 can move following the extension protrusion 31. According to the limit of the sliding mouth 22, the moving path and moving distance of the opening and closing member 4 can be accurately determined.

[0051] At least one group of detection components 6 is also provided on the moving frame 2 on both sides of the opening and closing member 4. This embodiment takes one group as an example. When there are multiple groups, they can be set on the moving frame 2 on both sides of the opening and closing member 4, or be set on the moving frame 2 in parallel along the opening path of the sliding opening 22, and the detection component 6 is in abutment with the opening and closing member 4. When the telescopic member 3 is pulled by the hand wheel, the opening and closing member 4 is driven to move by the extending protrusion 31, thereby opening and closing the detection component 6, thereby realizing the detection of the high-voltage switch cabinet or circuit breaker by the detection component 6.

[0052] Among them, the detection component 6 can detect the following: temperature detection, positioning detection, humidity detection, leakage detection, etc.

[0053] Among them, the detection component 6 can be set according to the closing locking point. If there are two closing locking points, the detection component 6 is set at both closing locking points. In this way, when the transmission screw 21 moves, various data of the high-voltage switch cabinet or circuit breaker in different states can be detected respectively at the two combinations of closing locking points.

[0054] Furthermore, the telescopic part 3 matches the style of the telescopic groove 210. Style matching means that the structures are interlocked. For example, when the telescopic groove 210 adopts a hexagonal groove or a rectangular groove, the telescopic part 3 adopts a hexagonal rod or a rectangular rod. When the telescopic groove 210 adopts a circular groove, the telescopic part 3 adopts a circular rod, and an extension protrusion 31 is provided on the circular rod, and the extension protrusion 31 is used to engage with the sliding mouth 22. Therefore, the circular rod will also be limited and cannot rotate. Therefore, it can also be adapted to the needs. The specific style is determined according to the needs. This method enables the telescopic part 3 to fit the wall of the telescopic groove 210 to reduce the generation of gaps and ensure that the position of the telescopic part 3 will not shift when moving along the telescopic groove 210, so that the opening and closing effect of the opening and closing part 4 on the detection component 6 is more stable.

[0055] The telescopic member 3 is located at one end of the static frame 1 and is provided with a pulling head 32. The pulling head 32 is larger than the notch of the telescopic slot 210, so that the telescopic member 3 cannot continue to fully extend into the telescopic slot 210. At the same time, a pulling point is provided to facilitate the pulling and movement of the telescopic member 3. The style of the pulling head 32 can be consistent with the style of the end of the transmission screw 21 at this end. If the end style of the transmission screw 21 is a hexagonal block structure, the style of the pulling head 32 can also adopt a hexagonal block structure, so that the pulling head 32 fits with the end of the transmission screw 21. When the handwheel is engaged, rotating the pulling head 32 can also drive the transmission screw 21 to rotate.

[0056] The telescopic member 3 and the pulling head 32 can both be made of insulating materials, such as plastic, to provide good insulation effect.

[0057] In order to improve the stability of pulling, friction grooves can be provided on the surface of the pulling head 32, and friction grooves can also be provided at the contact point between the hand wheel and the pulling head 32.

[0058] Further, refer to Figure 2 As shown, the transmission screw 21 is divided into three sections. The first section is a threaded section 211, which is connected to the static frame 1. The threaded section 211 is the longest and can account for two-thirds of the length of the transmission screw 21, so as to drive the dynamic frame 2 to move.

[0059] The second section is a smooth opening section 212 , and the sliding opening 22 is opened with the opening section 212 . The opening section 212 has no threads, so that the opening and closing member 4 can be easily moved along the sliding opening 22 without being affected by the threads.

[0060] The third section is a solid section 213, which is pivotally connected to the moving frame 2. The interior of the solid section 213 is solid, that is, the telescopic slot 210 does not extend to the solid section 213. The solid section 213 can ensure gravity stability. At the same time, a pivot opening is opened on the side of the moving frame 2 away from the stationary frame 1, and the solid section 213 is located in the pivot opening for easy pivoting.

[0061] Specifically, the transmission screw 21 is divided into three sections, each corresponding to a different function. The cooperation between the threaded section 211 and the fixing nut ensures the stable movement of the dynamic frame 2. The opening section 212 is no longer provided with threads to ensure the stable movement of the opening and closing member 4. The solid section 213 ensures gravity balance and at the same time ensures the stability of the pivot connection.

[0062] In some embodiments, reference Figure 3 As shown, the detection component 6 includes a guide rail 61, an opening and closing frame 62, a second elastic member 63 and a first sensor 64; the guide rail 61 and the first sensor 64 are both arranged on the moving vehicle frame 2, and the first sensor 64 is located at one end of the guide rail 61, and the opening and closing member 4 is located at the other end of the guide rail 61. The first sensor 64 can adopt any required sensor structure such as a temperature sensor, a humidity sensor, a leakage current sensor, a photoelectric sensor, etc., and the guide rail 61 can adopt any special-shaped rail structure such as a T-rail, an I-rail, etc.

[0063] The opening and closing frame 62 is slidably connected to the guide rail 61, and one end extends to the opening and closing part 4 and abuts against the opening and closing part 4, and the other end is spaced a preset distance from the first sensor 64. The preset distance is the distance that the opening and closing frame 62 can be pushed when it is pushed by the opening and closing part 4. When the opening and closing frame 62 is pushed by the opening and closing part 4 and slides toward the first sensor 64 along the guide rail 61, it gradually moves to the first sensor 64, so that the switch of the first sensor 64 is pressed against the opening and closing frame 62 to realize the opening of the first sensor 64. After the opening and closing frame 62 is separated from the first sensor 64, the first sensor 64 is closed.

[0064] Among them, the end of the opening and closing frame 62 close to the opening and closing member 4 is an arc-shaped end portion to facilitate the pushing of the opening and closing member 4.

[0065] A connecting ring 611 is also provided on the guide rail 61, and the connecting ring 611 is sleeved on the outer wall of the opening and closing frame 62. One end of the second elastic member 63 is connected to the connecting ring 611, and the other end is wrapped around the opening and closing frame 62 and connected to the opening and closing frame 62. The second elastic member 63 can be a spring, and the elastic force of the first elastic member 5 is greater than the elastic force of the second elastic member 63, so that when the opening and closing member 4 is acted upon by the elastic force of the first elastic member 5, it can push the opening and closing frame 62 to overcome the elastic force of the second elastic member 63 and move toward the first sensor 64, and open the first sensor 64.

[0066] Among them, the guide rail 61 is also provided with a limiting protrusion for limiting the moving path of the opening and closing frame 62. A connecting protrusion can be set on the opening and closing frame 62, and the limiting protrusion can cooperate with the connecting protrusion to limit the moving path of the opening and closing frame 62.

[0067] Specifically, when the detection component 6 needs to be opened, the opening and closing member 4 is pushed by the elastic force of the first elastic member 5 to push the opening and closing frame 62, and the opening and closing frame 62 overcomes the elastic force of the second elastic member 63 and moves along the guide rail 61, and abuts against the first sensor 64 switch, thereby opening the first sensor 64. When the first sensor 64 needs to be closed, the opening and closing member 4 is driven by the telescopic member 3 to move along the sliding opening 22, and when it is separated from the opening and closing frame 62, the opening and closing frame 62 is reset by the elastic force of the second elastic member 63, and separated from the first sensor 64 switch, and the first sensor 64 is closed, so as to open and close the first sensor 64. The opening and closing of the first sensor 64 is used to perform data detection on the chassis and the high-voltage switchgear or circuit breaker.

[0068] In some embodiments, a switching component 7 is further provided on the moving vehicle frame 2 and is arranged parallel to the transmission screw 21. The switching component 7 is in contact with the opening and closing component 4. The switching component 7 is used to provide switching when detecting other data, so that the original data detection will not affect the detection of another set of data.

[0069] For further reference, Figure 4 and Figure 5As shown, the switching assembly 7 includes a parallel rail 71, a switching frame, an abutment frame and a second sensor 74; the parallel rail 71 is installed on the moving vehicle frame 2 and is parallel to the transmission screw 21. The switching frame is slidably connected to the parallel rail 71, so that when the telescopic member 3 drives the opening and closing member 4 to move, the switching frame and the parallel rail 71 can be accurately driven to move on the same parallel moving path.

[0070] The first sensor 64 and the second sensor 74 are both installed on the switching frame, so that when the switching frame moves, it can switch the positions of the first sensor 64 and the second sensor 74, thereby turning on different sensors. Among them, the second sensor 74 can be used as a single-touch leakage current sensor for leakage detection when replacing high-voltage switchgear or circuit breakers.

[0071] The abutment frame is connected to the switching frame and abuts against the opening and closing part 4. By utilizing the abutment effect between the abutment frame and the opening and closing part 4, when the opening and closing part 4 is pulled by the telescopic part 3, it can drive the opening and closing part 4 to move, so that the abutment frame pulls the switching frame to move, thereby pulling the second sensor 74 to the position corresponding to the opening and closing frame 62. At the same time, the opening and closing frame 62 is synchronously pushed by the opening and closing part 4 to open the second sensor 74.

[0072] Specifically, when the telescopic member 3 pulls the opening and closing member 4 to move, the opening and closing member 4 drives the switching frame to move by pushing the abutment frame, so that the first sensor 64 on the switching frame moves, and the second sensor 74 is moved to the corresponding position of the opening and closing frame 62. At the same time, the opening and closing member 4 synchronously pushes the opening and closing frame 62, so that the opening and closing frame 62 contacts the switch of the second sensor 74, thereby turning on the second sensor 74. The second sensor 74 can adopt a leakage current sensor to detect whether there is leakage in the chassis vehicle and the switch cabinet, and the hand wheel and the telescopic member 3 are both made of insulating materials. Therefore, when pulling, even if there is leakage, it will not affect the user.

[0073] In some embodiments, reference Figure 5 As shown, the opening and closing member 4 has two groups of relatively arranged conical sleeves, namely the first conical sleeve 41 and the second conical sleeve 42. According to the structure of the conical sleeve, the surface of the first conical sleeve 41 is a conical surface, and one end is a vertical plane in the vertical direction. The conical surface of the first conical sleeve 41 abuts against the opening and closing frame 62, and the plane end of the first conical sleeve 41 abuts against the switching component 7. When the conical surface of the first conical sleeve 41 moves along the opening and closing frame 62, the opening and closing frame 62 is pushed to move along with the position of the conical surface. When the first conical sleeve 41 moves to the switching component 7, the plane end pushes the abutment frame of the switching component 7 to move, thereby changing the position of the second sensor 74, and synchronously driving the second conical sleeve 42 to move.

[0074] When the second conical sleeve 42 moves onto the opening and closing frame 62, it synchronously pushes the opening and closing frame 62 to move, and at the same time, the second sensor 74 gradually moves to the contact point of the opening and closing frame 62 until the switch of the second sensor 74 contacts the opening and closing frame 62, thereby opening the second sensor 74.

[0075] The second sensor 74 is a leakage current sensor with a touch-type opening and closing, that is, when the opening and closing frame 62 contacts the switch of the second sensor 74, the second sensor 74 can detect leakage in the surrounding area. When the telescopic part 3 is released, the telescopic part 3 is driven by the first elastic part 5 to return to the telescopic groove 210, the opening and closing frame 62 is disengaged from the switch of the second sensor 74, and the second sensor 74 can be closed.

[0076] Another way is that the second sensor 74 is a leakage current sensor that is opened and closed in a click-type manner, that is, after the opening and closing frame 62 contacts the switch of the second sensor 74, the second sensor 74 is in a long-open state. When the opening and closing frame 62 contacts the switch of the second sensor 74 again, the second sensor 74 is closed. The two opening and closing methods can be determined according to needs.

[0077] For further reference, Figure 5 and Figure 6 As shown, a separation opening 43 is further provided on one side of the first conical sleeve 41 and the second conical sleeve 42. When the conical sleeve rotates, the separation opening 43 is located at the abutment frame or the opening and closing frame 62, so that the abutment frame or the opening and closing frame 62 passes through the separation opening 43. The setting of the separation opening 43 can allow the first conical sleeve 41 and the second conical sleeve 42 to have a freer movement space. When the transmission screw 21 rotates, it can drive the first conical sleeve 41 and the second conical sleeve 42 to rotate, so that the position of the separation opening 43 of the first conical sleeve 41 and the second conical sleeve 42 changes. When it rotates to the opening and closing frame 62 or the abutment frame, the opening and closing frame 62 or the abutment frame can pass through the separation opening 43, so that the conical sleeve is not affected by the opening and closing frame 62 and the abutment frame and continues to move. This method can facilitate the transmission screw 21 to move over the opening and closing frame 62 and the abutment frame, that is, it is convenient to separate the moving frame 2 from the static frame 1 for maintenance or repair.

[0078] Among them, a mark of the position of the separation opening 43 can be set at the pulling head 32, and a mark of the opening and closing frame 62 or the abutting frame can also be set on the surface of the static frame 1 to facilitate the user to observe the position of the separation opening 43 and the position of the abutting frame or the opening and closing frame 62 with the naked eye.

[0079] In some embodiments, reference Figure 4As shown, the moving frame 2 is also provided with an electric drive assembly 8, which is connected to the transmission screw 21 and provides a driving function. The arrangement of the electric drive assembly 8 enables the structure on the chassis to be selectively driven manually or rotated electrically. When manually driven, the transmission screw 21 can be driven to rotate by a hand wheel when there is no power supply, and the electric drive assembly 8 can be used for driving when there is power supply. The driving mode can be selected by the user.

[0080] At the same time, the electric drive component 8 is also connected to the detection component 6 and the switching component 7 to provide a driving function synchronously, and can synchronously open the detection component 6 and the switching component 7 to improve the function of intelligent control.

[0081] Furthermore, the electric drive assembly 8 includes a motor 81, a sprocket group 82, a driving cylinder 83 and a push frame; the motor 81 is installed on one side of the moving frame 2, and the linkage wheel group is composed of two sprockets and a chain, and one sprocket is connected to the motor 81, and the other sprocket is connected to the transmission screw 21, so that when the motor 81 drives the sprocket to rotate, the chain drives the sprocket connected to the transmission screw 21 to rotate, thereby realizing the effect of electric drive.

[0082] The driving cylinder 83 and the transmission screw 21 are arranged parallel to the moving vehicle frame 2, and the telescopic end is connected to the abutment frame. Therefore, when the telescopic end of the driving cylinder 83 is extended or contracted, the abutment frame can be driven to move, and the abutment frame is used to drive the switching frame or the opening and closing component 4 to move, thereby realizing automatic switching and automatic opening and closing of the sensor.

[0083] Among them, reference Figure 7 As shown, a delay cylinder 84 is provided between the telescopic end of the driving cylinder 83 and the abutment frame. A delay space exists in the delay cylinder 84. The delay space is utilized to prevent the abutment frame from being affected by the telescopic end when it moves. When the telescopic end is extended or retracted, it passes over the delay cylinder 84 and then pushes the abutment frame to move.

[0084] Through the electric drive component 8, the dynamic and static frames 1 can be automatically driven to separate, and the pushing effect of the opening and closing parts 4 can be used to realize automatic switching and automatic opening and closing of the sensor. However, if there is insufficient power supply, such as the internal battery is dead or the circuit is short-circuited, the manual method is more convenient and safer.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
