Description

Technical Field

[0001] This utility model relates to the field of cold and heat source equipment control technology, and in particular to an energy-saving control device for cold and heat source equipment. Background Technology

[0002] A heating and cooling source device is a temperature control machine that integrates heating and cooling functions. It is widely used in shopping malls and other places. Also known as a central air conditioning system, when installed and used inside a plaza, due to environmental factors, the central air conditioning system operates at partial load for most of the time under the influence of indoor and outdoor operating conditions and simultaneous usage coefficients. The central air conditioning heating and cooling source device (i.e., the main unit) only controls the output based on the supply and return water temperatures, which cannot effectively guarantee the needs of the terminal units. At the same time, it cannot guarantee the reasonable and efficient operation of the main unit. This inevitably leads to the central air conditioning system operating at over-output power, resulting in a low energy efficiency ratio and a significant waste of energy. Therefore, installing a control device to rationally allocate energy to the heating and cooling source device and improve its efficiency is crucial for energy saving.

[0003] Existing technologies, such as patent CN204153916U, disclose an energy-saving control device for a cold and heat source equipment. This patent uses a central processing unit (CPU) connected to a power supply unit, a data acquisition unit, a communication unit, a control unit, and an operating platform. The control unit is connected to the central air conditioning cold and heat source equipment, a bypass detection unit, and an alarm unit. This utility model device solves the problem of energy waste caused by excessive output power of existing air conditioning cold and heat source equipment.

[0004] In daily work, during the installation and use of equipment, because the existing equipment is installed outdoors, it is easily affected by external forces and the control area is accidentally touched, causing unnecessary operation of the equipment, making it difficult for the equipment to control the cold and heat source equipment to save energy. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the control area of ​​the equipment is easily accidentally touched, making it difficult for the equipment to properly control the cold and heat source equipment. Therefore, this invention proposes an energy-saving control device for cold and heat source equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an energy-saving control device for cold and heat source equipment, comprising a body, a mounting plate, a display screen, a control area, and a plug. The mounting plate is fixedly connected to the side of the body, the display screen is fixedly connected to the surface of the body, the control area is fixedly connected to the surface of the body, and the plug is inserted into the upper end of the body. A protective device is fixedly provided on the surface of the body, the protective device comprising a rotating block and a protective cover.

The rotating rods are rotatably connected inside the rotating hole. A groove is provided at one end of the rotating rod away from the rotating block, and a pulling rod is slidably connected inside the groove.

[0007] Furthermore, a first spring is fixedly connected to one end of the pull rod that slides within the groove, and the end of the first spring away from the pull rod is fixedly connected to the inside of the groove. By setting the first spring, a reset force can be applied to the pull rod, reducing the situation where the pull rod is difficult to reset and the insertion rod is tightly stuck inside the slot during use.

[0008] Furthermore, a plug is fixedly connected to the end of the pull rod away from the first spring, and the plug is provided to facilitate the protection of the protective cover.

[0009] Furthermore, the protective cover has a slot on its side, and the insert rod is inserted into the slot.

[0010] Furthermore, an anti-detachment device is fixedly installed on the upper end of the main body. The anti-detachment device includes a connecting block and a moving rod. The connecting block is fixedly connected to the upper surface of the main body. The moving rod is slidably connected inside the connecting block. A pressure plate is fixedly connected to one end of the moving rod. A connecting plate is fixedly connected to the end of the moving rod away from the pressure plate. A sliding rod is fixedly connected between the pressure plate and the connecting plate. The sliding rod is slidably connected inside the connecting block. A second spring is sleeved and connected to the surface of the sliding rod. By setting the pressure plate, it is convenient to move the moving rod and the sliding rod, reducing the situation where the moving rod and the sliding rod move quickly and accurately during the use of the equipment.

[0011] Furthermore, one end of the second spring is fixedly connected to the surface of the pressure plate, and the other end of the second spring away from the pressure plate is fixedly connected to the surface of the connecting block. The second spring is provided to facilitate the application of a restoring force to the pressure plate.

[0012] Furthermore, a positioning rod is fixedly connected to one end of the connecting plate near the plug. The positioning rod is inserted inside the plug, and the positioning rod is provided to facilitate limiting the position of the plug.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this utility model, by setting a protective device, the control area of ​​the equipment body is effectively protected, which plays a role in protecting the equipment from being operated. This reduces the possibility of the control area being accidentally touched by external forces during the use of the existing equipment, causing unnecessary operation of the equipment and making it difficult to control the cold and heat source equipment for energy saving. This protective device can shield and protect the control area of ​​the equipment body, thus improving the practicality of the equipment.

[0015] In this invention, by setting an anti-detachment device, the plug is effectively limited, which stabilizes the plug and reduces the possibility that the plug may be easily hit by external force, causing it to detach from the equipment body and affecting the normal use of the equipment. This anti-detachment device can keep the plug firmly inside the body, thus improving the stability of the equipment. Attached Figure Description

[0023] The specific design and function of its protective device 6 and anti-detachment device 7 will be explained below.

[0024] In this embodiment: a protective device 6 is fixedly installed on the surface of the main body 1. The protective device 6 includes a rotating block 62 and a protective cover 61. The rotating block 62 is fixedly connected to the lower end surface of the main body 1. The protective cover 61 is attached to the surface of the main body 1. A rotating hole 63 is opened at one end of the protective cover 61 near the rotating block 62. A rotating rod 64 is fixedly connected to both ends of the rotating block 62. The rotating rod 64 is rotatably connected inside the rotating hole 63. A groove 65 is opened at one end of the rotating rod 64 away from the rotating block 62. A pull rod 66 is slidably connected inside the groove 65. The pull rod 66 is L-shaped.

[0025] Specifically, a first spring 67 is fixedly connected to one end of the pull rod 66 that slides within the pull groove 65, and the end of the first spring 67 that is away from the pull rod 66 is fixedly connected to the inside of the pull groove 65.

[0026] In this embodiment: by setting the first spring 67, a reset force can be applied to the pull rod 66, reducing the situation where the pull rod 66 is difficult to reset and tightly engages the insertion rod 68 with the slot 69 during use.

[0027] Specifically, a plug rod 68 is fixedly connected to the end of the pull rod 66 away from the first spring 67. The plug rod 68 is provided to facilitate the protection of the protective cover 61.

[0028] Specifically, the protective cover 61 has a slot 69 on its side, and the insert rod 68 is inserted into the slot 69.

[0029] In this embodiment: an anti-detachment device 7 is fixedly installed on the upper end of the main body 1. The anti-detachment device 7 includes a connecting block 71 and a moving rod 72. The connecting block 71 is fixedly connected to the upper surface of the main body 1. The moving rod 72 is slidably connected inside the connecting block 71. One end of the moving rod 72 is fixedly connected to a pressure plate 73. The end of the moving rod 72 away from the pressure plate 73 is fixedly connected to a connecting plate 74. A sliding rod 76 is fixedly connected between the pressure plate 73 and the connecting plate 74. The sliding rod 76 is slidably connected inside the connecting block 71. A second spring 77 is sleeved and connected to the surface of the sliding rod 76.

[0030] In this embodiment, by setting the pressure plate 73, it is convenient to move the moving rod 72 and the sliding rod 76, thereby reducing the need for the moving rod 72 and the sliding rod 76 to move quickly and accurately during the use of the equipment.

[0031] Specifically, one end of the second spring 77 is fixedly connected to the surface of the pressure plate 73, and the other end of the second spring 77 away from the pressure plate 73 is fixedly connected to the surface of the connecting block 71. The second spring 77 is provided to facilitate the application of a restoring force to the pressure plate 73.

[0032] Specifically, a positioning rod 75 is fixedly connected to one end of the connecting plate 74 near the plug 5. The positioning rod 75 is inserted inside the plug 5. The positioning rod 75 is provided to facilitate the limiting of the plug 5.

[0033] Working principle: When the equipment is in operation, the user pulls the lever 66 to stretch the first spring 67. Then, the lever 66 drives the insert 68 to move and disengage from the slot 69. Immediately, the protective cover 61 is released from its restraint and rotates to detach from the surface of the main body 1. By setting up the protective device 6, the control area 4 of the main body 1 is effectively protected, which plays a role in protecting the equipment from being operated. This reduces the possibility of the control area 4 being accidentally touched by external forces during the use of the existing equipment, which could lead to unnecessary operation of the equipment and make it difficult to control the cold and heat sources for energy saving. This protective device 6 can shield and protect the control area 4 of the main body 1, improving the practicality of the equipment.

[0034] When the device pulls out plug 5, the user presses the pressure plate 73, causing the moving rod 72 and the sliding rod 76 to move inside the connecting block 71. When the sliding rod 76 and the pressure plate 73 move, they compress the second spring 77, generating elastic force. Then, the positioning rod 75 on the surface of the connecting plate 74 moves away from the inside of plug 5, and plug 5 is released from its restraint and pulled out. By setting the anti-detachment device 7, plug 5 is effectively limited, which plays a role in stabilizing plug 5 and reducing the possibility that plug 5 is easily impacted by external forces, causing plug 5 to detach from the device body 1 and affecting the normal use of the device. This anti-detachment device 7 can stabilize plug 5 inside the body 1, improving the stability of the device.
