Description

Technical Field

[0001] The present invention relates to the technical field of power control, and particularly to a dedicated data acquisition device for a power control system. Background Art

[0002] Since we have invented more power-consuming products such as computers and household appliances, when dealing with power control, a collector is usually required. A collector is an intelligent device controlled by a microprocessor, and its function is to collect the electrical pulse signals of multiple meters and convert them into digital data information for recording and storage. Therefore, it is called a data collector, or simply a collector for short. In the system, it communicates with a concentrator through an RS-485 communication cable or a 220V power line carrier, receives various commands sent by the concentrator, and transmits the recorded user meter data and status to the concentrator. The collector can also communicate with a hand-held device on-site through an infrared communication interface, receive various commands sent by the hand-held device, and transmit various data recorded by the collector. The collector uses EEPROM to form a data storage unit and adopts the latest clock chip, which has leap year correction and can automatically adjust for the millennium bug problem and months with less than 31 days, ensuring that the real-time clock is preserved for ten years and the data is retained for 40 years when the collector loses power. The collector has a complex tariff function, and up to 24 time periods can be set every day, and different tariffs such as valley, flat, peak, and spike can be charged.

[0003] However, during the implementation of the above technical solutions, it is found that at least the following technical problems exist:

[0004] However, for the use and installation of the data collector, it is usually installed in a data acquisition box and used in combination with its components. However, the traditional data acquisition box is exposed to the outside world and will be affected by the external environment, which is conducive to moisture and mosquitoes entering the device and damaging the circuit. The existing technology is to install a dehumidification box inside the housing to adsorb the moisture inside the housing, but it can only perform the function of dehumidification, and at the same time, it will not cause air circulation inside the device. The overall design is single, and it will also cause external insects to enter the device during the dehumidification process, resulting in poor use effects. Summary of the Invention

[0045] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0046] Embodiment 1:

[0047] This embodiment introduces the specific structure of a dedicated data acquisition device for a power control system. As Figures 1-7 shown, a control panel 4 is installed on the front side of the data acquisition box 2. The control panel 4 can use a PLC226 model control chip to achieve self-programming program control, and can control the electrical appliances in the entire device. This will not be described in detail here. A frame for protecting the box body is welded on the outside of the data acquisition box 2, and a supporting base 1 is welded on the bottom side of the frame. Legs are provided at the four corners of the base 1, and the legs at this place form a gap between the base 1 and the ground, facilitating the installation of other structural components; the data collector 5 is installed in the data acquisition box 2. Here, the data collector 5 is used as the core component of the entire device and can collect power data in real time. Its working principle is specifically explained and described in the background technology; the dehumidification component is installed on the bottom side of the data acquisition box 2, and the dehumidification component includes an air pump 6 and a three-way valve 10 installed at the air port of the air pump 6. The three-way valve 10 is controlled by the control panel 4;

[0048] Among them, the air extraction port 9 on the three-way valve 10 is communicated with the inner cavity of the data acquisition box 2. An inlet cover 3 is provided below the data acquisition box 2. The specific position of the inlet cover 3 can be referred to Figure 1 to see, and two sets of wire clamping sacs 12 are arranged in the inlet cover 3. The data line passes between the two sets of wire clamping sacs 12 and enters the data acquisition box 2, and is connected to the wiring port 23 provided on the data collector 5. The air release port 11 on the three-way valve 10 is communicated with the two sets of wire clamping sacs 12, that is, the three-way valve 10 makes adjustments according to the operation mode of the air pump 6. At the same time, the air pump 6 adopts an automatic air extraction and inflation pump structure with two modes of inflation + air extraction.

[0049] In some examples, a pipeline is provided between the air release port 11 and the two sets of wire clamping sacs 12. Tooth openings are provided on the opposite sides of the two sets of wire clamping sacs 12. When the wire clamping sacs 12 are inflated, the two sets of wire clamping sacs 12 move towards each other, and the clamping and positioning process of the data line can be completed.

[0050] In some examples, the inlet cover 3 is connected to the bottom side of the data acquisition box 2 by a connecting member 14, and a wire passing port 15 is opened on the top side of the inlet cover 3. The wire passing port 15 allows the data line to pass through and enter the data acquisition box 2. The data line enters from the area between the two sets of wire clamping sacs 12, passes through the wire passing port 15, and finally enters the data acquisition box 2 and is connected to the data collector 5.

[0051] In some examples, rubber protrusions 13 are provided on the opposite sides of the two sets of wire clamping sacs 12. Grooves for the rubber protrusions 13 to pass through are opened on the surface of the inlet cover 3. The diameter of the end of the rubber protrusion 13 is greater than the diameter of the groove. Refer to Figure 4 to see, and the specific operation process for specifically installing the wire clamping sac 12 is as follows:

[0052] Place the wire clamping bladder 12 into the wire inlet cover 3;

[0053] Then, squeeze the rubber protrusion 13 to cause elastic deformation of the rubber protrusion 13, and pass through the corresponding notch, so as to achieve the state as shown in Figure 3 shown.

[0054] In a specific application scenario, the air pump 6 and the three-way valve 10 are opened. At this time, the air pump 6 is switched to the inflation mode. Refer to Figure 3 to see the inflation path indicated by the arrow. When the inflation process of the two groups of wire clamping bladders 12 is completed, the data cable passing through the wire inlet cover 3 is clamped by the wire clamping bladder 12 to ensure that the data cables are arranged side by side and regularly. At the same time, several bristles 16 distributed up and down also approach each other to complete the semi-sealed treatment of the gap between the two groups of wire clamping bladders 12, preventing mosquitoes from entering the data acquisition box 2 through the gap between the two groups of wire clamping bladders 12 and the data cable.

[0055] In some examples, several bristles 16 are arranged on the opposite sides of the two groups of wire clamping bladders 12. The several bristles 16 corresponding up and down are symmetrically distributed in an inclined manner, and the bristles 16 corresponding up and down are always in a crossed distribution state. The distribution state of the bristles 16 here can be referred to Figure 7 to see.

[0056] By adopting the above technical solutions:

[0057] A dehumidification component is designed in the data acquisition box 2. The air pump 6 is used to complete the suction treatment of the moisture in the inner cavity of the data acquisition box 2. At the same time, the air pump 6 can also complete the inflation treatment of the wire clamping bladder 12, complete the clamping and positioning treatment of the data cable, and prevent the data cable from being randomly distributed. At the same time, the use of the wire clamping bladder 12 can handle various specifications of wires, and with the help of the bristles 16, the problem that mosquitoes enter the box body through the large gap between the data acquisition box 2 and the wire and damage the equipment can be solved.

[0058] Among them, an auxiliary dehumidification structure can be selectively used. The specific content is as follows:

[0059] In some examples, a ventilation top cover 8 is arranged on the top of the data acquisition box 2. Several partition plates 7 are embedded in the data acquisition box 2, and the partition plates 7 are used to divide the inner cavity area of the data acquisition box 2, and a mesh plate 24 for air flow to pass through is arranged on the partition plates 7; the mesh plate 24 is in a long strip shape, and the mesh plate 24 is connected to the corresponding partition plate 7 by a rotating shaft, and several packets of desiccant 25 are filled in the inner cavity of the mesh plate 24.

[0060] When specifically used, since the end of the mesh plate 24 is open, the desiccant 25 can be put into the mesh plate 24 from the opening, and then rotate the mesh plate 24 to make it presentFigure 2 In the state shown, when the desiccant in the wire mesh cover plate 24 needs to be replaced, the wire mesh cover plate 24 can be manually flipped so that the desiccant falls out.

[0061] Among them, magnetic adsorption layers are provided on the outer walls of the wire mesh cover plate 24. The wire mesh cover plate 24 can be magnetically connected to the corresponding partition plate 7 in a magnetic adsorption manner and is flush with the upper and lower surfaces of the partition plate 7.

[0062] By adopting the above technical solution:

[0063] A wire mesh cover plate 24 is provided on the partition plate 7 in the data acquisition box 2, and desiccant can be selectively placed. During the suction treatment, the air flow passes through the desiccant in the wire mesh cover plate 24, so that the moisture in the acquisition box can be removed, ensuring the long-term operation of the equipment in the data acquisition box 2.

[0064] Embodiment 2:

[0065] Different from Embodiment 1, this embodiment introduces the specific structure of the buffer component in a special data acquisition device for a power control system, as Figures 2-6 shown. The data collector 5 is located at the bottom of the inner cavity of the data acquisition box 2, and the data collector 5 is suspended and installed by setting a buffer component. The buffer component includes a rod component and a spring group. The buffer component here ensures the normal use of the data collector 5.

[0066] Among them, the rod component includes a top rod 18 and a bottom rod 17 that are arranged vertically in the inner cavity of the data acquisition box 2. An upper slider 20 is movably sleeved on the surface of the top rod 18, and a lower slider 19 is movably sleeved on the surface of the bottom rod 17. A rotating rod is provided between the lower slider 19 and the data collector 5 for connection. The specific installation method is as Figure 6 shown;

[0067] The spring group includes a longitudinal spring 21 and a transverse spring 22. The longitudinal spring 21 is used to connect the data collector 5 and the upper slider 20. The transverse spring 22 is sleeved on the surface of the bottom rod 17 and connects the data acquisition box 2 and the corresponding lower slider 19. The longitudinal spring 21 and the transverse spring 22 here are made of the same material, both made of carbon steel, and have good elasticity.

[0068] In some examples, linear distribution of track grooves is provided on the bottom arm of the data acquisition box 2. A T-shaped sliding member is welded on the surface of the lower slider 19, and the sliding member is arranged in the track groove in a matching manner. When the lower slider 19 slides on the surface of the bottom rod 17, the transverse spring 22 can undergo an elastic deformation of a certain degree of movement and drive the lower slider 19 to quickly return to the initial state. During the movement of the lower slider 19, the sliding member can be driven to move in the track groove, ensuring the stability of the movement of the lower slider 19.

[0069] By adopting the above technical solution:

[0070] By using the spring group in the buffer component, it can be ensured that when the whole device is impacted or a geological disaster occurs, the damage degree of the data collector 5 as the core component is greatly reduced. The force in the horizontal direction can be offset by the elastic deformation of the horizontal spring 22, and the force in the vertical direction can be offset by the elastic deformation of the vertical spring 21, thus ensuring the normal use of the data collector 5.

[0071] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the present invention.
