Description

Technical Field

[0001] The utility model relates to the technical field of central air conditioners, in particular to a central air conditioner operation warning device. Background Art

[0002] The central air-conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the cooling and heating loads of the indoor environment.

[0003] The refrigeration system is a crucial component of a central air conditioning system. Its type, operating mode, and structural form directly impact its economical, efficient, and rational operation. The main principle is to utilize the latent heat absorbed during the vaporization process of a liquid. Furthermore, the boiling point of a liquid varies with pressure, with lower pressure resulting in a lower boiling point. Central air conditioning refrigeration systems can be categorized as vapor compression or absorption refrigeration, depending on how heat is transferred from a high-temperature object to a low-temperature object. However, regardless of the refrigeration method, the system essentially consists of three components: a distribution box or cabinet, a main unit, and a water pump.

[0004] In recent years, with the further high-quality and in-depth development of my country's social economy and the continuous improvement of people's living standards, the application scope of central air-conditioning systems has become increasingly wider, and the number of users has also increased day by day. Consequently, the requirements for the operation and management of central air-conditioning systems in various aspects have also increased. Its operation and management is an important component of modern property equipment management. If the operation and management work is not done well, it will lead to problems such as unsatisfactory air conditioning effects, frequent equipment failures, and risk accidents. In the daily management process, the inspection and maintenance of each part of the central air-conditioning system, as well as its normal operation, require signs to display the equipment status and permitted operations in the corresponding time period. For example, a sign reading "Operating" is hung in the "Operation" state, or a sign reading "Do not close" is hung in the "Stop State" state. This ensures that the equipment will not be accidentally operated by a third party during this period, causing accidents or illegal operation that may cause equipment damage. However, the traditional method of attaching signs to the corresponding equipment by simply hanging ropes is not very ideal. The sign can only be installed by hanging, which is not very adaptable. Therefore, it is necessary to design a central air-conditioning operation warning device for this purpose. Utility Model Content

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The central air-conditioning operation warning device of the preferred embodiment of the present utility model is as follows: Figure 1-7As shown, the device includes a vertically arranged square shell 10, and a display screen module 20 and a status display button 30 arranged on the front side wall of the shell; wherein, the display screen module 20 specifically includes a display screen body 21 and a control mainboard (not shown) for controlling the display screen body, the control mainboard is arranged inside the square shell, and there are generally multiple status display buttons 30, such as corresponding host keys, water pumps and distribution cabinet keys, etc. The control mainboard is also used to communicate with the central air-conditioning system in the background, and cooperate with the status display button to achieve that when the maintenance personnel press the corresponding button, the control mainboard controls the display screen body to display the operating status and running number of the corresponding equipment. For example, when the status display button 30 corresponding to the host is pressed, the running number of multiple host devices and the status of each one are displayed on the display screen body, such as showing that one of the hosts is in normal operation, another is under maintenance, and the others are in a shutdown state. It should be emphasized that the connection between the control mainboard and the central air-conditioning system is common knowledge in the industry and will not be repeated in this solution.

[0029] Furthermore, the device includes a rotating base 40 that is horizontally rotatably mounted on the top end surface of the square housing 10, and an arm assembly 50 that is rotatably mounted on the rotating base 40. The rotating base 40 and the arm assembly 50 form a unit, with two units provided, one at each of the left and right ends of the square housing 10. The arm assembly 50 includes a first arm 51 that is mounted on the rotating base 40 in a longitudinally damped rotational direction, and a second arm 52 that is connected to the first arm 51 in a damped rotational manner. The free ends of the two second arms 52 are detachably connected by a connecting assembly 60, allowing for easy opening or connection to form a closed ring structure. A stopper 70 is provided at the upper end of the square housing 10, between the two rotating seats 40, for limiting the position of the first arm 51 after it has rotated toward the rear center of the square housing 10. The stopper 70 may be a C-shaped ring adapted to the diameter of the first arm 51, or two cooperating magnetic members, one of which is provided on the first arm 51 and the other on the square housing 10. Alternatively, other structures may be used to prevent the first arm 51 from moving in this position. During use, the left and right first arms 51 are adjusted to a longitudinal position and the free ends of the two second arms 52 are connected via the connecting assembly 60. This allows for a tethered installation. The first arms 51 are then flipped downward and rearward, allowing the free ends of the first arms 51 to rest against the tabletop. The arms are then unfolded and flipped downward to support the display module 20 in a tilted position. The preferred method of use can be selected based on the application. Compared to traditional lanyard structures, this solution offers greater adaptability.

[0030] In this embodiment, a rotating groove 80 is provided at the upper end of the square shell 10 for the horizontal rotation of the rotating seat 40, so as to limit the rotation of the rotating seat 40 and make the top of the square shell 10 more tidy, thereby preventing the rotating seat 40 from protruding from the top surface of the square shell 10. Furthermore, an avoidance notch 90 is provided on the rear inner wall of the rotating groove 80 to avoid the first arm 51, so that the first arm 51 can be lower than or flush with the top surface of the square shell 10 after being flipped backward.

[0031] The top of the square shell 10 is provided with a cover plate 100, and the top of the rotating seat 40 is against the cover plate 100 to prevent the rotating seat 40 from moving upward during the rotation process; the cover plate 100 is provided with an avoidance hole 110 corresponding to the first arm 51 for its back and forth swinging. Furthermore, the top of the square shell 10 is provided with two grooves 120 between the two rotating grooves 80, and the two grooves 120 are directly connected to the two rotating grooves 80 respectively. The rear ends of the grooves 120 directly penetrate the rear side wall of the square shell 10. The groove 120 is specifically triangular when viewed from above, and the end corresponding to its bottom side is connected to the rotating groove 80, wherein the groove 120 and the cover plate 100 jointly form a limit member 70, so that after the first arm 51 rotates horizontally into the groove 120, it can prevent the first arm 51 from moving upward through its inner side wall and the cover plate 100, thereby preventing the first arm 51 from moving upward when the second arm 52 is tilted and supported on the table, causing the square shell 10 to tip backward.

[0032] In this embodiment, the connecting assembly 60 includes two third arms 61, which are respectively connected to the two second arms 52 with damped rotation. A T-shaped hole 130 is radially penetrated through the side wall of the left third arm 61, and the longitudinal end of the T-shaped hole 130 extends through the free end surface of the corresponding third arm 61. Furthermore, the connecting assembly 60 also includes a T-shaped piece 140 provided on the right third arm 61 and adapted to the T-shaped hole 130. The longitudinal end of the T-shaped piece 140 is in the same direction as the right third arm 61. When the first arm 51 and the second arm 52 are adjusted into place, the T-shaped piece is inserted parallel to the T-shaped hole 130, thereby connecting the two second arms 52 together and preventing the two second arms 52 from axially separating.

[0033] Furthermore, positioning protrusions 150 are provided on the inner walls at both ends of the radial direction of the T-shaped hole 130 to prevent the T-shaped piece 140 from falling off radially. Specifically, positioning protrusions 150 are provided on both sides of the circumference of the same end of the T-shaped through hole. The two positioning protrusions 150 and the inner wall of the longitudinal end of the T-shaped hole 130 together enclose a positioning cavity 160 for positioning the transverse end of the T-shaped piece 140. The transverse end of the T-shaped piece 140 is disc-shaped and its longitudinal end is coaxially and detachably connected to the corresponding third arm 61. Specifically, the longitudinal end of the T-shaped piece 140 and the corresponding third arm 61 are coaxially threaded. By placing the transverse end of the T-shaped piece 140 in the positioning cavity 160, the stability of the connection can be further improved.

[0034] In addition, the material of the third arm 61 and the T-shaped piece 140 can be set to magnetic metal, and a magnet 170 can be set on the longitudinal end of the T-shaped piece 140. Then, when the lateral end of the T-shaped piece 140 is placed in the positioning cavity 160, the T-shaped piece 140 can be prevented from loosening out of the T-shaped hole 130 circumferentially in the movable cavity. During specific use, the lateral section of the T-shaped piece and the magnet 170 are inserted into the T-shaped hole from the side of the lateral end of the T-shaped hole away from its longitudinal end. When the T-shaped piece is coaxial with the T-shaped hole, the lateral end of the T-shaped piece and the magnet 170 are axially moved into the positioning cavity 160 and adsorbed on the inner wall of the positioning cavity.

[0035] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
