Description

Technical Field

[0001] The utility model belongs to the technical field of electrical room temperature and humidity control, and in particular relates to an intelligent control device for electrical room temperature and humidity of a portal crane. Background Art

[0002] The loading and unloading tasks of ships are heavy, and the utilization rate of gantry cranes is high. The core of the gantry crane's electric control system is PLC and inverter, which are installed in the electrical room. Since the working environment temperature and humidity are the main factors affecting the performance of the electric control system, during the long-term operation of the gantry crane, the electric control system generates a lot of heat, causing the temperature and humidity in the electrical room to be high. In the long run, it will have an adverse effect on the life and performance of electrical components, and then cause electrical failures, increase maintenance costs, and affect production operations. Utility Model Content

[0003] The utility model aims to provide an intelligent control device for the temperature and humidity of the electrical room of a gantry crane, so as to solve the technical problem that the temperature and humidity in the air chamber are too high, which affects the life and performance of electrical components, thereby causing electrical failures, increasing maintenance costs and affecting production efficiency.

[0004] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: an intelligent control device for electrical room temperature and humidity of a portal crane, comprising a temperature and humidity transmitter and a locking mechanism for placing the temperature and humidity transmitter, and a fixing mechanism for fixing the temperature and humidity transmitter on the locking mechanism, the locking mechanism comprising a connecting block, a slot is provided in the connecting block, the slot is a non-circular slot, a plug block corresponding to the slot is provided on one side of the temperature and humidity transmitter, and the temperature and humidity control device comprises a control system connected to the temperature and humidity transmitter;

[0005] The fixing mechanism comprises a fixing frame arranged outside the temperature and humidity transmitter and the connecting block, and a baffle for fixing and combining the temperature and humidity transmitter and the locking mechanism is arranged on one side of the fixing frame.

[0006] Preferably, the connecting block is provided with slide grooves on opposite sides, and the slide grooves are provided with locking blocks for fixing the fixing frame to the temperature and humidity transmitter and the outer side of the connecting block.

[0007] Preferably, a plurality of springs are provided between the slide groove and the locking block.

[0008] Preferably, two ends of the spring are fixedly connected to one side of the locking block and the inner wall of the sliding groove respectively.

[0009] Preferably, locking grooves are provided on opposite sides of the fixing frame.

[0010] Preferably, the control device includes a door machine PLC, an electrical room air conditioner, and a fault touch screen, and the door machine PLC, temperature and humidity transmitter, the electrical room air conditioner and the fault touch screen are connected via a data transmission line.

[0011] The utility model of an intelligent control device for electrical room temperature and humidity of a portal crane has the following advantages:

[0012] 1. This kind of intelligent control device for electrical room temperature and humidity of a gantry crane inserts a temperature and humidity transmitter into the connecting block through the setting of a connecting block, a locking block, a fixing frame and a locking groove. The fixing frame is installed on the outside of the temperature and humidity transmitter and the connecting block. The locking block is inserted into the locking groove to lock the fixing frame on the outside of the connecting block. The fixing frame fixes the temperature and humidity transmitter on the connecting block through a baffle, which makes it more convenient to disassemble and install the temperature and humidity transmitter and saves installation time.

[0013] 2. This kind of intelligent control device for the temperature and humidity of the electrical room of a gantry crane first installs a temperature and humidity transmitter in the electrical room to monitor the ambient temperature and humidity of the electrical room in real time. Secondly, PLC programming and automatic control are used to adjust and use two electrical room air conditioners to control the temperature and humidity of the electrical room. During operation, if the temperature and humidity transmitter monitors that the temperature or humidity of the electrical room reaches the set upper limit, the outer air conditioner 2 is automatically started to perform auxiliary work until the temperature drops to 30°C or the humidity drops to 55%. The outer air conditioner 2 automatically stops to achieve the requirements of energy saving and consumption reduction. Finally, if the temperature and humidity transmitter monitors that the temperature or humidity of the electrical room reaches the set upper limit during operation, it can issue an alarm by itself, and at the same time transmit the alarm signal to the fault touch screen through PLC communication, so as to remind and inform the operator and maintenance personnel, so that the temperature and humidity of the electrical room will not affect the performance and life of the electrical components, and will not affect the production efficiency.

[0028] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below with reference to the accompanying drawings, which is an intelligent control device for electrical room temperature and humidity of a portal crane.

[0029] like Figure 1-Figure 4 As shown, the utility model is an intelligent control device for electrical room temperature and humidity of a portal crane, comprising a temperature and humidity transmitter 1 and a locking mechanism 2 for placing the temperature and humidity transmitter 1, and a fixing mechanism 3 for fixing the temperature and humidity transmitter 1 on the locking mechanism 2, the locking mechanism 2 comprising a connecting block 21, a slot 22 is arranged in the connecting block 21, the slot 22 is a non-circular slot, a plug block corresponding to the slot 22 is arranged on one side of the temperature and humidity transmitter 1, and the temperature and humidity control device comprises a control system connected to the temperature and humidity transmitter 1;

[0030] The fixing mechanism 3 includes a fixing frame 31 arranged outside the temperature and humidity transmitter 1 and the connecting block 21. The fixing frame 31 matches the shape of the temperature and humidity transmitter 1 and the connecting block 21. A baffle 32 for fixing the temperature and humidity transmitter 1 and the locking mechanism 2 is provided on one side of the fixing frame 31. Four baffles 32 are provided.

[0031] In this embodiment, the temperature and humidity transmitter 1 is inserted into the connecting block 21, and the fixing frame 31 is installed outside the connecting block 21 and the temperature and humidity transmitter 1.
