A distributed energy storage scheduling device

Abstract

This invention relates to a distributed energy storage scheduling device, comprising a housing and a cover. A smart meter module is disposed within the housing. The housing has a wiring port, and the cover is disposed at the wiring port. The cover is inserted into the wiring port from left to right. The cover or the housing has an elastic element that applies elastic force to the cover, causing it to press against the housing in a front-to-back engagement. One of the housing and the cover has a slot, and the other has a locking block that engages with the slot. After the cover is inserted, the locking block engages with the slot under the action of the elastic element, restricting the cover's lateral movement. When removing the cover, pressing the cover disengages the locking block from the slot. By applying elastic force to the cover through the elastic element, and after insertion, the cover and housing are prevented from moving relative to each other in the lateral direction due to the action of the locking block and the slot. When removing the cover, simply pressing the cover separates the locking block from the slot, thus improving the efficiency of cover removal and installation.

Description

Technical Field

[0001] This invention relates to a distributed energy storage scheduling device. Background Technology

[0002] Smart meters are used for dispatching electricity from the power grid to users. Smart meters are intelligent terminals in the smart grid. Besides the basic electricity metering function of traditional meters, to adapt to smart grid applications, smart meters also have intelligent functions such as bidirectional multi-rate metering, user-end control, bidirectional data communication with multiple data transmission modes, and anti-theft features. Smart meters are also a type of energy storage dispatching device, widely used in distributed energy storage systems.

[0003] During installation and use, the cable is led out from the bottom of the smart meter. Currently, smart meters usually use bolts to fix a transparent cover to protect the cable. This installation method requires disassembling each bolt one by one when replacing the cable, which is quite troublesome and has low disassembly and assembly efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a distributed energy storage scheduling device to solve the technical problem of low efficiency in disassembling and assembling the casing of current smart meters.

[0005] The distributed energy storage scheduling device of the present invention adopts the following technical solution:

[0006] A distributed energy storage dispatching device includes:

[0007] The outer casing, including the housing and the cover;

[0008] The smart meter module is housed inside the casing and has wiring terminals;

[0009] The housing is provided with a wiring port for wiring operations of the terminal blocks, and the housing cover is provided at the wiring port to seal the wiring port;

[0010] The cover is inserted into the wiring port from left to right, and the housing has a slot at the wiring port for the cover to be inserted from left to right.

[0011] The cover or the housing is provided with an elastic element that applies elastic force to the cover so that the cover and the housing are pressed together from front to back;

[0012] One of the housing and the cover has a slot, and the other has a block that engages with the slot. After the cover is inserted into place, the block engages with the slot under the action of the elastic element to restrict the left and right movement of the cover. When removing the cover, pressing the cover can make the block leave the slot.

[0013] Beneficial effects: The distributed energy storage scheduling device of the present invention has a slot at the wiring port, and the shell cover is installed at the wiring port by insertion. The shell cover is elastically applied by an elastic element. After insertion, the shell cover and the shell are not moved relative to each other in the left and right directions by the action of the locking block and the locking groove. When the shell cover needs to be removed, it is only necessary to press the shell cover to separate the locking block and the locking groove to pull out the shell cover. Compared with the traditional method of fixing the shell cover with bolts, the distributed energy storage scheduling device of the present invention can improve the efficiency of shell cover installation and removal.

[0014] Furthermore, a side baffle is provided on the left end of the cover facing the housing. After the cover is inserted into place, the side baffle engages with the left side wall of the housing and covers the slot opening. Covering the slot opening with the side baffle improves the protection level of the housing.

[0015] Furthermore, the cover is provided with a mounting groove. The cover includes a cover body and a pressure plate movably disposed on the cover body. An elastic element is disposed in the mounting groove and located between the cover body and the pressure plate. The elastic element applies elastic force to the cover by pressing the cover against the cover through the pressure plate. Pressing the cover against the cover by the pressure plate facilitates the installation of the cover.

[0016] Furthermore, the pressure plate is provided with a stop block, and the groove wall of the mounting slot is provided with a stop block mating groove. The stop block is movably configured within the stop block mating groove, and the stop block mating groove has a stopping side wall that engages with the stop block to prevent it from dislodging. By preventing the pressure plate from dislodging from the mounting slot, the movement of the pressure plate is more stable, further facilitating the installation of the pressure plate.

[0017] Furthermore, at least two stops are provided. This improves the anti-detachment effect on the pressure plate.

[0018] Furthermore, the elastic element is a spring, and the cover has a spring groove in which the spring is hung. The spring has a simple structure and is easy to install.

[0019] Furthermore, the pressure plate remains within the mounting groove during its forward and backward movement and slides in a guide engagement with the groove wall. This guide engagement between the pressure plate and the groove wall ensures stable operation and facilitates installation.

[0020] Furthermore, the locking block is disposed on the housing, and the locking slot is disposed on the housing cover. Before the housing cover is inserted into place, the side of the housing cover facing away from the housing slides in engagement with the locking block, and the side of the housing cover facing the housing slides in engagement with the housing. Both the front and rear sides of the housing cover have limit positions during insertion, preventing wobbling during installation and facilitating alignment of the locking block and the locking slot.

[0021] Furthermore, the card blocks are arranged in pairs, and the two card blocks in a pair are symmetrical vertically. This improves the restraining effect on the cover plate.

[0022] Furthermore, the locking block and the locking slot engage in a front-to-back pressing action to achieve front-to-back pressing of the housing and the cover, thus simplifying the housing structure. Attached Figure Description

[0034] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0035] Specific embodiment 1 of the distributed energy storage scheduling device of the present invention:

[0036] like Figures 1 to 6 As shown, a distributed energy storage scheduling device includes a housing 1, a smart meter module, and a mounting base 2. The mounting base 2 is fixed to the rear side of the housing 1, and the smart meter module is fixed inside the housing 1. The smart meter module has wiring terminals. The specific structure of the smart meter module is existing technology and will not be described in detail here.

[0037] The outer casing 1 includes a housing 11 and a cover 12. The housing 11 has a wiring port for wiring operations to the terminals. A slot is formed at the wiring port on the housing 11 for the cover 12 to be inserted from left to right. The cover 12 is inserted into the slot at the wiring port from left to right to seal the wiring port. This insertion method facilitates the installation and removal of the cover 12, improving efficiency. For ease of operation, anti-slip protrusions 121 are provided on the side of the cover 12 facing away from the housing 11.

[0038] The cover 12 is provided with a spring 3 that applies elastic force to the cover 12, causing the cover 12 to press against the housing 11. In this embodiment, the cover 12 is provided with a mounting groove 122. The cover 12 includes a cover body 123 and a pressure plate 124 movably disposed on the cover body 123. The spring 3 is disposed in the mounting groove 122 and between the cover body 123 and the pressure plate 124. The spring 3 presses against the housing 11 through the pressure plate 124, thereby applying elastic force to the cover 12. The cover body 123 is provided with a spring groove 125, and a hanging lug 126 is provided at the opening of the spring groove 125, on which the spring 3 is hung.

[0039] The pressure plate 124 has two symmetrically arranged stops 127. The mounting groove 122 has a stop-block mating groove 128 on its wall. The stops 127 are movably positioned within the stop-block mating groove 128. The stop-block mating groove 128 has a stop sidewall 1281 that engages with the stops 127 to prevent them from dislodging. During its forward and backward movement, the pressure plate 124 remains within the mounting groove 122 and slides in a guide engagement with the groove wall. Through the stop engagement between the stops 127 and the stop sidewall 1281, the pressure plate 124 will not dislodge from the mounting groove 122.

[0040] The cover 123 has a slot 1231, and the housing 11 has a locking block 111 that engages with the slot 1231. After the cover 12 is inserted into the slot 1231, the locking block 111 engages with the slot 1231, restricting the left and right movement of the cover 12. When removing the cover 12, pressing the cover 12 can cause the locking block 111 to disengage from the slot 1231. In this embodiment, the locking block 111 is provided on the housing 11, and the slot 1231 is provided on the cover 12. During the insertion process and before the cover is fully inserted, the side of the cover 12 facing away from the housing 11 is slidably engaged with the locking block 111. During the insertion process and before the cover is fully inserted, the pressure plate 124 is located in the mounting groove 122, and the side of the cover 12 facing the housing 11 is slidably engaged with the housing 11. This provides stability during the insertion of the cover 12 and facilitates its insertion.

[0041] In this embodiment, after the cover 12 is inserted into place, under the action of the spring 3, the locking block 111 and the bottom wall of the slot 1231 engage in a front-to-back blocking action to achieve front-to-back pressing of the housing 11 and the cover 12. In other embodiments, depending on actual needs, two sliding grooves with opposite upper and lower openings can be provided at the wiring port, and the upper and lower sides of the cover are respectively inserted into the sliding grooves. At this time, the locking block is set on the groove wall of the sliding groove.

[0042] A side baffle 129 is provided on the left side of the cover 12 facing the housing 11. After the cover 12 is inserted into place, the side baffle 129 is engaged with the left side wall 112 of the housing 11 and covers the slot opening, thereby improving the protection level of the wiring port.

[0043] When installing the casing 12 of the distributed energy storage scheduling device of the present invention, insert the casing 12 into the slot at the wiring port from left to right until the locking slot 1231 and the locking block 111 are aligned front to back. Under the action of the spring 3, the casing 12 moves forward, and the locking block 111 engages with the locking slot 1231. At this time, the casing 12 cannot move left or right, and the casing 12 is fully inserted. When it is necessary to open the casing 12, press the casing 12 to separate the locking block 111 from the locking slot 1231, and then pull out the casing 12.

[0044] In other embodiments, the card blocks can be set in two or more pairs, with the two card blocks in each pair being symmetrical vertically. Of course, in other embodiments, one or more odd numbers of card blocks can also be set.

[0045] In other embodiments, the cover may not have a side baffle, in which case a gap is left between the cover and the housing, which is suitable for conditions with a better external environment.

[0046] In other embodiments, an elastic rubber block can be used instead of a spring. In this case, a pressure plate is not required, and the elastic rubber block rests directly against the housing. In other embodiments, a rubber ring can be used instead of a spring. The rubber ring is located on the side of the cover facing the housing and extends along the outer periphery of the cover. After the rubber ring deforms, it provides a better sealing effect between the cover and the housing.

[0047] In other embodiments, a pressure plate and a spring can also be provided on the housing to apply elastic force to the housing cover.

[0048] In other embodiments, one end of the spring can be directly fixed to the cover by means of adhesive bonding, bolt fixing, or other methods.

[0049] In other embodiments, the pressure plate can extend out of the mounting groove. In this case, relatively movable guide posts and guide sleeves can be added between the pressure plate and the cover to make the pressure plate and the cover slide in a guided manner. Of course, it is also feasible for the pressure plate and the cover not to have a guided sliding relationship.

[0050] In other embodiments, the slot may be provided on the housing, and the block may be provided on the cover.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
