DETAILED DESCRIPTION

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] like Figures 1 to 5 As shown, an embodiment of the present invention provides a door lock for an outdoor terminal station of a cable, comprising: a mounting assembly, which is constructed to be mounted on a door panel; a locking assembly 6, which includes a locking member 62 and a first lock tongue 5, and the first lock tongue 5 is constructed to be mounted on a door frame; a monitoring assembly, which is arranged on the mounting assembly, and the monitoring assembly includes a pressure detection element 8 and a signal processing element 9 electrically connected to the pressure detection element 8, and along a first direction, the pressure detection element 8, the locking member 62 and the first lock tongue 5 are arranged in sequence, and the locking member 62 is movably arranged on the mounting assembly along the first direction so that the locking member 62 has a locking position in which it is locked with the first lock tongue 5 and an unlocking position away from the first lock tongue 5 and acts on the pressure detection element 8.

[0030] In the above technical solution, the mounting assembly is securely mounted on the door panel, and the locking member 62 is capable of switching between a locked position and an unlocked position. When the door lock is in the locked state, the locking member 62 cooperates with the first lock tongue 5, and the pressure detection element 8 is in a non-stressed state. When the door lock is unlocked, the locking member 62 moves in the first direction and abuts the pressure detection element 8. This action converts force into an electrical signal, which is captured and processed by the signal processing element 9. The signal processing element 9 is electrically connected and can receive and analyze the electrical signal from the pressure detection element 8 to determine the real-time state of the door lock. Once the unlocked state is detected, the signal processing element 9 will wirelessly transmit the door lock state information to the multi-function monitoring host in the substation through its built-in communication module. The host further analyzes and processes the data and transmits the state information to a remote monitoring center via the power dedicated network, thereby realizing remote monitoring of the cable terminal station door lock. In this way, not only real-time monitoring of the door lock state is achieved, but also the overall cost of the door lock with monitoring function is reduced. This allows the monitoring function to be deployed in a more economical manner at the outdoor terminal station of the high-voltage cable while maintaining high performance, thereby improving the safety and management efficiency of the power facilities.

[0031] In some embodiments, when the locking member 62 is in the locked position, the locking member 62 can also act on the pressure detection element 8. However, the forces exerted on the pressure detection element 8 by the locking member 62 are different when the locking position and the unlocked position. When the force changes, it can be known that the door lock is unlocked.

[0032] In some embodiments, the pressure detection element 8 is a pressure-sensitive sensor, which can be a piezoelectric sensor and does not need to be connected to a power supply. Alternatively, a piezoresistive sensor can be used, in which case a power supply from the power supply element 10 is required.

[0033] In some embodiments, the signal processing element 9 includes a collector and a communication module. The collector is used to receive and convert the signal of the pressure detection element 8, and the communication module is used to transmit the signal of the collector to the multi-functional monitoring host in the substation. The collector collects the pressure-sensitive signal and processes it into door lock status information, and the communication module transmits the door lock status information to the multi-functional monitoring host set in the substation. Figure 1 As shown, signal processing element 9 is positioned below pressure sensing element 8 and is electrically connected to pressure sensing element 8 via a communication line. Power supply element 10 is positioned to the right of signal processing element 9 and provides DC power to signal processing element 9 via a power line. The elastic member 71, pressure sensing element 8, signal processing element 9, and power supply element 10 constitute a technical security monitoring module.

[0034] like Figure 1As shown, in an embodiment of the present invention, the monitoring assembly further includes an elastic member 71 located between the pressure detection element 8 and the locking member 62, the locking member 62 is in a locked position, and both ends of the elastic member 71 abut against the locking member 62 and the pressure detection element 8 respectively.

[0035] In the above technical solution, the elastic member 71 adopts a spring. Through the deformation and recovery of the spring, it is ensured that the locking member 62 can accurately abut the pressure detection element 8 when in the unlocked position, thereby realizing the effective transmission of the pressure signal. In which, the locking member 62 remains in cooperation with the first lock tongue, and the spring is in a natural state. When unlocked, the locking member 62 moves and compresses the spring, and the spring transmits the force to the pressure detection element 8.

[0036] In some embodiments, the elastic member 71 may be made of a rubber pad or other elastic materials, which can also achieve a buffering effect.

[0037] like Figure 1 As shown, in an embodiment of the present invention, the monitoring assembly further includes a guide sleeve 72 disposed on the mounting assembly. The guide sleeve 72 is located on the periphery of the elastic member 71. The end of the locking member 62 facing away from the first locking tongue 5 extends into the guide sleeve 72 and is capable of acting on the elastic member 71. Thus, the guiding effect of the guide sleeve 72 not only improves the movement accuracy of the locking member 62, but also enhances the stability and service life of the entire monitoring assembly. Furthermore, the guide sleeve 72 can effectively isolate the elastic member 71 from the external environment, reducing its direct exposure to air, thereby extending the service life of the elastic member 71 and reducing maintenance and replacement costs.

[0038] In some embodiments, the guide sleeve 72 can be designed into various shapes, such as square or oval, as long as it can guide the locking member 62 .

[0039] In some embodiments, as Figure 1 As shown, the pressure detection element 8 is located on the left side of the elastic member 71, and the sensing surface on the right side of the pressure detection element 8 abuts against the elastic member 71. The guide sleeve 72 is a transparent plastic tube. Along the first direction, the length of the right side of the elastic member 71 is less than 1 cm of the length of the right side of the transparent plastic tube, that is, the elastic member 71 is located in the guide sleeve 72, and the inner diameter of the transparent plastic tube is slightly larger than the outer diameter of the locking bolt 621. When the locking bolt 621 is in the locked position, the right side of the elastic member 71 and the left side of the locking bolt 621 are in a naturally relaxed abutting state, and the left side 1 cm of the locking bolt 621 is located in the transparent plastic tube.

[0040] In some embodiments, the elastic member 71 is set to a force value range of 1N-5N, that is, the force value of the elastic member 71 from the beginning of deformation to the maximum deformation is set to 1N-5N, the pressure sensitive signal is collected by the collector, and the alarm information is transmitted to the substation station monitoring host. The monitoring host transmits the state information of the door lock to the monitoring center through the power special network.

[0041] As shown in Figure 1 In the embodiments of the present application, the monitoring assembly further comprises a power supply element 10, and the power supply element 10 is electrically connected with the signal processing element 9. In this way, the long-term stable operation of the monitoring assembly is ensured through the continuous power supply of the power supply element 10.

[0042] In some embodiments, the power supply element can also be powered by an external power supply, such as direct power supply through a cable.

[0043] In some embodiments, the power supply element 10 is a DC (Direct Current) power supply.

[0044] In the prior art, most of the ordinary padlocks used in the outdoor terminal stations and towers of high-voltage cables are subjected to rain after being used outdoors, and the lock eye will rust, which makes it difficult to open and easy to damage the key when trying to open it, which greatly affects the development of on-site operation and maintenance work, and also has certain requirements for the use environment. Therefore, in view of the use scene and the current situation of ordinary padlocks, a waterproof door lock box is provided, and a monitoring function of the state of the door lock is added. Specifically, as shown in Figure 1 In the embodiments of the present application, the installation assembly comprises a waterproof box body 1 for enclosing a containing cavity and a waterproof box cover 2, the waterproof box cover 2 is rotatably connected with the waterproof box body 1, the waterproof box body 1 is installed on the door plate, the waterproof box body 1 is provided with a first through hole 11, the first lock tongue 5 extends into the containing cavity through the first through hole 11, and the first lock tongue 5 is provided with a locking through hole matched with the locking member 62.

[0045] In the above technical solution, the combination of the waterproof box body 1 and the waterproof box cover 2 forms a sealed containing cavity, which effectively isolates the external moisture, effectively prevents rainwater from entering, protects the lock body assembly from rust, and prolongs the service life of the door lock; and the first through hole 11 on the waterproof box body 1 cooperates with the locking through hole of the first lock tongue 5, so that the locking member 62 can freely move in the locking through hole, realizing the opening and closing of the door lock.

[0046] In some embodiments, the volume of the containing cavity is 30cmx28cmx5cm, and the locking assembly 6, the elastic member 71, the pressure detection element 8, the signal processing element 9, and the power supply element 10 are installed on the waterproof box body 1 by small bolts and are sealed and protected by the containing cavity.

[0047] like Figure 1 As shown, in an embodiment of the present invention, the locking assembly 6 also includes a second lock tongue 4, which is constructed to be installed on a door panel, a second through hole 12 is provided on the waterproof box body 1, and the second lock tongue 4 extends into the accommodating cavity through the second through hole 12, and the second lock tongue 4 is provided with a guide through hole; the locking member 62 includes a lock bolt 621 and a lock plate 622 connected to the lock bolt 621, the first end of the lock bolt 621 can be locked with the locking through hole, the second end of the lock bolt 621 passes through the guide through hole and is set toward the pressure detection element 8, and the lock bolt 621 slides with the guide through hole.

[0048] In the above technical solution, the second lock tongue 4 and the first lock tongue 5 both cooperate with the locking member 62 to realize the complete door lock function, thereby enhancing the anti-destruction ability and anti-theft performance of the door lock; and the waterproof box body 1 can also be fixed to the door panel through the second lock tongue 4 to increase the installation stability of the waterproof box body 1.

[0049] In some embodiments, a guide through hole is provided at one end of the second lock tongue 4, and the other end of the second lock tongue 4 is fixedly connected to the door panel. A locking through hole is provided on one end of the first lock tongue 5, and the other end of the first lock tongue 5 is fixedly connected to the door frame. The second lock tongue 4 and the first lock tongue 5 cooperate with the locking component 62 to achieve a strong connection between the waterproof box body and the terminal station door body.

[0050] In some embodiments, the first through hole 11 and the second through hole 12 are both bar-shaped through holes.

[0051] like Figure 1 and Figure 2 As shown, in an embodiment of the present invention, the locking assembly 6 also includes a lock plate 61 installed on the waterproof box body 1, and the lock plate 61 includes: a fixed plate 611, which is connected to the waterproof box body 1; a limiting plate 612, which is connected to the fixed plate 611 and is arranged at an angle, and the limiting plate 612 is located on the side of the first lock tongue 5 facing the second lock tongue 4, and a limiting through hole is provided on the limiting plate 612. After the lock bolt 621 passes through the limiting through hole, it can cooperate with the locking through hole, and the lock bolt 621 slides with the limiting through hole.

[0052] In the above technical solution, the limiting plate 612 can limit the movement range of the lock bolt 621, thereby preventing the lock bolt 621 from being separated from the elastic component 71 or causing damage to the elastic component 71 due to excessive movement of the lock bolt 621; and through the limiting plate 612, and the lock bolt 621 passing through the limiting plate 612 and cooperating with the first lock tongue 5, the door lock can be more stably in a locked state.

[0053] In some embodiments, the limiting plate and the fixing plate are designed to have adjustable angles to facilitate installation of the locking bolt 621 .

[0054] like Figure 1 and Figure 2 As shown, in the embodiment of the present invention, a first locking plate hole 624 and a second locking plate hole 623 are provided on the locking plate 622, and the first locking plate hole 624 and the second locking plate hole 623 are spaced apart along the first direction. The locking plate 61 also includes a tongue 613 connected to the fixing plate 611 and arranged at an angle. When the locking member 62 is in the unlocked position, the first locking plate hole 624 of the first locking plate hole 624 and the second locking plate hole 623, which is close to the first locking tongue 5, cooperates with the tongue 613. When the locking member 62 is in the locked position, the second locking plate hole 623 of the first locking plate hole 624 and the second locking plate hole 623, which is close to the second locking tongue 4, cooperates with the tongue 613.

[0055] In the above technical solution, when the locking member 62 is in the locked position, the second locking plate hole 623 cooperates with the tongue 613, and the locking member 62 is fixed to prevent accidental unlocking; when in the unlocked position, the first locking plate hole 624 cooperates with the tongue 613, and the locking member 62 is fixed to prevent the lock bolt from moving and causing the door lock to be locked, so that misoperation can be avoided.

[0056] In some embodiments, a hanging hole 614 is provided on the tongue 613. When the locking member 62 is in the locked position, the hanging hole 614 is used to hang a door lock to close the door of the cable terminal station.

[0057] In some embodiments, the second buckle 3, the first locking tongue 5 and the second locking tongue 4 are all fixed by spot welding.

[0058] In some embodiments, the upper end of the locking piece 622 is fixedly connected to the locking bolt 621 by being integrally formed.

[0059] In some embodiments, when the waterproof box body 1 is installed on the door panel, the second lock tongue 4 just penetrates the second through hole 12, the left side of the lock bolt 621 penetrates the guide through hole of the second lock tongue 4 to a certain position, and then the lock plate 61 is installed. The lock plate 61 is fixed in the waterproof box body 1, and the right side of the fixing plate 611 is fixedly connected to the limiting plate 612. The left side of the fixing plate 611 is provided with a mounting through hole, and the limiting through hole is provided on the limiting plate 612. After the lock plate 61 is fixedly installed, the lock bolt 621 moves to the right and penetrates the limiting through hole of the limiting plate 612 to reach a limited position. The lower part of the fixing plate 611 is provided with a tongue piece 613, and the tongue piece A hanging hole 614 is provided in the middle of 613, and the tongue piece 613 has a certain thickness. An anti-accidental touch component is embedded in its lower edge near the fixed plate 611. The head of the stopper 644 of the anti-accidental touch component has a certain curvature. The edge locking piece 622 of one of the first locking piece hole 624 and the second locking piece hole 623 can push the stopper 644 to compress the internal spring, and then the tongue piece 613 passes through one of the first locking piece hole 624 and the second locking piece hole 623. After it is in place, the stopper 644 resets and locks the locking piece 622. Then, the stoppers 644 on both sides are squeezed at the same time to release the lock.

[0060] In some embodiments, the inner diameter of the guide hole on the second lock tongue 4 and the diameter of the lock bolt 621 adopt a transition fit method, and the inner diameter of the limiting hole on the limiting plate 612 and the diameter of the lock bolt 621 adopt a transition fit method to ensure the stability of the left and right movement of the lock bolt 621.

[0061] like Figures 1 to 5 As shown, in an embodiment of the present invention, the locking assembly 6 also includes an anti-accidental touch component, which is arranged on one side of the tongue 613. The anti-accidental touch component includes: an elastic member 641, which is arranged on the tongue 613; a stop member 644, which is connected to the elastic member 641, and the stop member 644 is movably arranged on the tongue 613. The elastic member 641 is used to provide an elastic force to the stop member 644 away from the tongue 613.

[0062] In the above technical solution, when the door lock is in the locked state, the tongue 613 engages with the lock plate 622 through one of the first lock plate hole 624 and the second lock plate hole 623, ensuring that the lock bolt 621 is firmly positioned. At this time, the anti-accidental touch member comes into play, wherein the elastic member 641 is in a naturally extended state, exerting an elastic force on the stopper 644 away from the tongue 613, so that the stopper 644 protrudes from the surface of the tongue 613, thereby effectively blocking external forces attempting to erroneously operate the locking member 62 and preventing the door lock from being accidentally opened. When unlocking is required, the operator applies sufficient force to overcome the resistance of the elastic member 641, causing the stopper 644 to move toward the tongue 613, releasing the blockage on the locking member 62. Subsequently, the locking member 62 responds to the external operation and moves along the first direction to the unlocked position, separating from the first lock tongue 5 and abutting against the pressure detection element 8, triggering the monitoring mechanism. During the entire operation process, the anti-accidental touch component ensures the correct operation of the locking component 62, avoids safety hazards caused by accidental touch or unconscious action, and improves the safety performance and reliability of the door lock.

[0063] In some embodiments, the elastic member 641 is a spring.

[0064] In some embodiments, there are two stoppers 644, one along the Figure 2 In the up-down direction, the two stoppers 644 are spaced apart on the tongue 613 , and the stop sections 6442 of the two stoppers 644 face away from each other.

[0065] like Figure 5 As shown, in an embodiment of the present invention, the anti-accidental touch component also includes a guide member 643, which is a cylindrical structure with one end open and the other end closed. The elastic member 641 is located in the cylindrical structure, and one end of the elastic member 641 abuts against the closed end of the cylindrical structure, and the other end of the elastic member 641 abuts against the stop member 644, and the stop member 644 slides in cooperation with the cylindrical structure.

[0066] In the above technical solution, the elastic member 641 provides elastic force in the guide member 643 to ensure that the stop member 644 remains in the initial position when no external force is applied. When an external force is applied, the stop member 644 can move in the guide member 643 to ensure that the stop member 644 moves smoothly in a direction perpendicular to the first direction, thereby avoiding the deviation of the stop member 644 during the movement.

[0084] In the prior art, most of the general locks used by terminal stations and towers will rust after being exposed to precipitation outdoors, making it difficult to open and easily damaging the key when trying to open it, which greatly affects the development of on-site work. Especially during the current flood-prevention summer period, there is abundant rainfall, and two to three heavy rains can cause the lock core to rust, and only the method of frequently replacing the lock can be used. In this case, a cable outdoor terminal station door lock waterproof box device needs to be developed to protect the general lock, reduce or avoid the lock core from being washed by rainwater, causing the lock core to rust and be unable to be opened, greatly reducing the number of times and cost of replacing the general lock and general key, reducing the reserve amount of general locks for front-line teams, and improving the management and control capabilities of entering the site. Through comparative research on current waterproof box products, it is found that waterproof boxes applied to electrical lines, instruments, and electrical equipment were mostly iron metal waterproof boxes before 2000, and after 2000, China's technology developed rapidly, and plastic technology gradually improved, and plastic waterproof boxes gradually replaced metal waterproof boxes due to their low cost, good insulation, and high waterproof level. Compared with plastic waterproof boxes, metal waterproof boxes have better explosion-proof performance, better impact resistance, and better environmental adaptability, but the quality of metal waterproof boxes is significantly greater than that of plastic waterproof boxes, the insulation is poorer, and the cost is higher, so metal waterproof boxes are mainly used for large power distribution cabinets and switch boxes. At present, in the field of electric power application, there are many studies and products of waterproof boxes for preventing water from entering electrical lines, instruments, and equipment, but there is no research or product related to cable outdoor terminal station door lock waterproof boxes in the field of high-voltage cable operation and maintenance. In summary, the present application provides a door lock for a cable outdoor terminal station, which is applied to a high-voltage cable outdoor terminal station and has the advantages of waterproofness, good insulation, damage prevention, and low cost, and can improve the management and control level of entering the high-voltage cable terminal station site, bringing greater economic and social benefits to power cable operation and maintenance work. The door lock for the cable outdoor terminal station of the present application solves the following three technical problems:

[0085] (1) By comparing various materials used in waterproof box products, a material used in a waterproof box for a door lock for a cable outdoor terminal station is selected, or a combination of two materials is used to meet the requirements of waterproofness, structural strength, safety, and economy in practical applications.

[0086] (2) Generally, waterproof box products are installed by screw connection, and a door lock for a cable outdoor terminal station is designed to innovate in product size and installation method, solve the waterproof problem of the door lock, and not only make the product structure and installation method convenient and time-saving and labor-saving, but also have damage prevention, thereby improving the installation efficiency and the performance of the waterproof box.

[0087] (3) Generally, the monitoring function is not considered for the door lock of the cable outdoor terminal station. If the door lock monitoring function is added, its technical implementation usually adopts human feature recognition sensing technology such as image and fingerprint or fully automatic smart lock technology, which is relatively expensive and has certain requirements for the use environment. It is not suitable for the door lock use scenario of the cable outdoor terminal station tower. If a low-cost waterproof door lock device with monitoring function can be designed under the premise of fully considering the use requirements and economic efficiency of the waterproof device, it can effectively monitor and protect the cable terminal station and tower, which has very high technical value.

[0088] Therefore, the present application provides a door lock for an outdoor cable terminal station, which can achieve the following technical effects:

The locking component 6, the elastic member 71, the pressure-sensitive sensor, the signal processing element 9, and the power supply element 10 are installed according to a certain layout design and are sealed and protected by the receiving cavity. The size of the receiving cavity, the overall layout of the design, and the implementation of the function have good applicability to the existing door locks of the cable outdoor terminal station.

[0091] (3) The present invention designs a waterproof box body snap-on installation method, in which the strip-shaped through hole on the left side of the waterproof box body 1 corresponds to the second lock tongue 4, and then the second clip 3 is inserted into the second card slot 13 near the edge of the waterproof box body 1 to lock it, so that the waterproof box body 1 and the door panel can be fixedly installed, which reduces the installation process, is convenient to install, saves time and effort, and improves the installation efficiency; at the same time, a method is cleverly designed to cooperate with the first through hole 11 and the second through hole 12 on the waterproof box body 1 and the first lock tongue 5, the second lock tongue 4 and the locking assembly 6 on the terminal station door body to achieve a strong connection between the waterproof box and the terminal station door body. Through the combination of the two design methods, the safety requirements of the power cable operation and maintenance for the waterproof door lock device are met, and the convenience of installation and use is also improved.

[0092] (4) The application designs a technical defense monitoring module, which has simple structure and strong functionality, realizes low-cost and high-practicability transformation of the cable terminal station door lock, increases the door lock state monitoring module including the sensor, the collector, the communication module, the power supply element 10, sets the pressure conduction spring force value range, sets the monitoring host data analysis threshold, timely sends the door lock state data to the monitoring center, and thus can better effectively monitor and protect the cable terminal station tower.

[0093] From the above description, it can be seen that the above-mentioned embodiments of the application achieve the following technical effects: the installation assembly is stably installed on the door plate, the locking member can be switched between the locking position and the unlocking position, when the door lock is in the locking state, the locking member cooperates with the first lock tongue, and the pressure detection element is in the non-stressed state; when the door lock is unlocked, the locking member moves along the first direction and abuts against the pressure detection element, which converts the force into an electrical signal, which is captured and processed by the signal processing element, the signal processing element can receive and analyze the electrical signal from the pressure detection element through electrical connection, and further judge the real-time state of the door lock, once the unlocking state is detected, the signal processing element will send the door lock state information to the multifunctional monitoring host in the transformer substation through the wireless way through the built-in communication module, the host further analyzes and processes the data, and transmits the state information to the remote monitoring center through the power special network, realizing the remote monitoring of the cable terminal station door lock. In this way, not only the real-time monitoring of the door lock state is realized, but also the overall cost of the door lock with monitoring function is reduced, so that the monitoring function can be deployed in the high-voltage cable outdoor terminal station in a more economical way while maintaining high performance, improving the safety and management efficiency of the power facilities.

[0094] The above only describes the preferred embodiments of the application and is not used to limit the application. For those skilled in the art, the application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the application shall be included in the protection scope of the application.
