Description

Technical Field

[0001] This utility model relates to the field of central air conditioning technology, specifically to a central air conditioning cooling circulating water dosing device. Background Technology

[0002] As the cooling circulating water of a central air conditioning system flows continuously, problems such as scale, algae, and corrosion frequently occur. The chemical dosing device used in central air conditioning systems can release scale inhibitors, add bactericides, and add corrosion inhibitors during use to ensure the normal flow of circulating water and the normal operation of the central air conditioning system.

[0003] Currently, some dosing devices are installed outdoors to avoid the chemicals being affected by indoor temperature and humidity. However, outdoor wind and rain can easily affect the metering and heat meters of the dosing device, thus affecting its normal operation. If the metering and heat meters are directly covered, their internal temperatures may be too high, affecting their normal operation and ultimately impacting the normal operation of the dosing device.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 As shown, the central air conditioning cooling circulating water dosing device includes a dosing equipment body 1, a bracket 6 welded to the surface of the dosing equipment body 1, and a meter 2, a heat meter 3, an inlet pipe 4, and an outlet pipe 5 installed on the top of the bracket 6. The inlet pipe 4 is connected to the water supply pipe of the central air conditioning system, and water from the water supply pipe can flow into the inlet pipe 4. The outlet pipe 5 is connected to the return water pipe of the central air conditioning system, and the outlet pipe 5 can inject the water that has undergone dosing into the circulation pipeline of the central air conditioning system through the return water pipe. A support mechanism 7 is installed on the top of the bracket 6.

[0025] The support mechanism 7 includes support rods 71 ​​that are detachably connected to both sides of the top of the bracket 6. A positioning component 72 is provided at the bottom of the support rod 71. The inner wall of the positioning component 72 is in contact with the surface of the bracket 6. A rain shield 8 is fixedly connected to the top of the support rod 71.

[0026] The positioning component 72 includes a U-shaped frame 721 welded to the bottom of the support rod 71. The inner wall of the U-shaped frame 721 is in contact with the surface of the bracket 6. A smooth rod 722 is fixedly connected to the top of the U-shaped frame 721. The top of the smooth rod 722 is fixedly connected to the top of the inner wall of the support rod 71. A lifting plate 723 is slidably sleeved on the surface of the smooth rod 722. Positioning rods 725 are fixedly connected to both sides of the bottom of the lifting plate 723. The positioning rods 725 slide through the top of the U-shaped frame 721 and the bracket 6. A compression spring 724 is sleeved on the surface of the smooth rod 722. When the operator pulls the lifting plate 723 upward, the compression spring 724 is compressed and the positioning rod 725 rises with the lifting plate 723. Then, under the action of the elastic force of the compression spring 724, the lifting plate 723 drives the positioning rod 725 to descend. The positioning rod 725 passes through the top of the U-shaped frame 721 and the bracket 6, thereby fixing the position of the support rod 71 at the top of the bracket 6.

[0027] The bottom of the rain shield 8 is fixedly connected to a diagonal brace 73 and an extension plate 9. The bottom of the diagonal brace 73 is in contact with the top of the bracket 6. The diagonal brace 73 increases the stability of the rain shield 8. The extension plate 9 is designed to be inclined to facilitate drainage. A shielding plate 10 is fixedly connected to one side of the bottom of the rain shield 8 and both sides of the bottom of the extension plate 9. There are several shielding plates 10, and adjacent shielding plates 10 are staggered. The shielding plates 10 can block rainwater and prevent rainwater from affecting the meter 2 and the heat meter 3.

[0028] A connecting mechanism 11 is installed at the bottom of the rain shield 8. The connecting mechanism 11 includes diamond-shaped blocks 111 fixedly connected to both sides of the rain shield 8. Connecting plates 112 are provided on both sides of the rain shield 8. A crossbar 113 is fixedly connected between the two connecting plates 112. The surface of the crossbar 113 is in contact with the surface of the bottom shield 10 of the rain shield 8. When the staff adjusts the position of the crossbar 113, the crossbar 113 can open the shield 10 so that the staff can inspect the meter 2 and the heat meter 3.

[0029] The surface of the connecting plate 112 is provided with a guide groove 114 and a circular groove 115. The surface of the rhombus block 111 is in contact with the inner walls of the guide groove 114 and the circular groove 115. The operator first pushes the connecting plate 112 obliquely upward. At this time, the rhombus block 111 cooperates with the guide groove 114 to guide the movement of the connecting plate 112. When the rhombus block 111 enters the interior of the circular groove 115, the operator can rotate the connecting plate 112. The crossbar 113 rotates accordingly to open the cover plate 10. After that, the operator pushes the connecting plate 112 obliquely downward. The rhombus block 111 re-cooperates with the guide groove 114. In this way, the tilt angle of the connecting plate 112 can be limited, and the crossbar 113 can stably open the cover plate 10.

[0030] The top of the rain shield 8 is provided with several drainage channels 12. The drainage channels 12 are designed to be inclined. The inclined drainage channels 12 can guide the rainwater on the top of the rain shield 8 so that the rainwater can flow to the top of the extension plate 9 and then flow down.

[0031] The top of the extension plate 9 is provided with a groove 13 and a slot 14. The groove 13 is designed to facilitate the collection of rainwater flowing down from the drainage channel 12. The groove 13 can discharge rainwater to both sides of the bracket 6. A rubber sheet 15 is embedded inside the slot 14. The pipe passes through the rubber sheet 15. The rubber sheet 15 is attached to the surface of the pipe, which can reduce the possibility of rainwater flowing downward through the pipe.

[0032] Working principle: After the operator pulls the lifting plate 723 upward, the U-shaped frame 721 can be placed on the surface of the bracket 6. Then, under the action of the compression spring 724, the lifting plate 723 drives the positioning rod 725 to descend. The positioning rod 725 passes through the top of the U-shaped frame 721 and the bracket 6. The support rod 71 can be stably placed on the top of the bracket 6. The rain shield 8, the extension plate 9 and the shielding plate 10 work together to shield and protect the meter 2, the heat meter 3, the water inlet pipe 4 and the water outlet pipe 5, avoiding damage to the meter 2, the heat meter 3, the water inlet pipe 4 and the water outlet pipe 5 caused by outdoor wind and rain.

[0033] In daily use, the staff can lift the connecting plate 112 diagonally upward to move the crossbar 113 upward. After that, the staff can rotate the connecting plate 112, and the crossbar 113 can be flipped over and the cover plate 10 at the bottom of the rain shield 8 can be opened. Based on this, the staff can inspect and maintain the meter 2 and the heat meter 3.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
