Description

Technical Field

[0001] The utility model relates to the field of electric power equipment, in particular to an air-conditioning load box. Background Art

[0002] The load box is a power detection device, which is mainly used to detect and maintain the load of generators, uninterruptible power supplies, and power transmission equipment. It is a tool for periodic testing and maintenance of generator sets. Its use avoids economic losses caused by failures in the startup or initial use of standby units or power supplies, and also provides a scientific basis for the detection of the load capacity of new units. Since the load box needs to perform multiple load tests, different resistance elements need to be replaced. Most of the load boxes on the market currently have different types of resistance elements fixed in the box. Although the functionality is improved, it also increases the structural design and load-bearing weight of the load box. In order to simplify the structure and facilitate maintenance and repair, a load box that can replace resistance elements is needed.

[0003] Chinese patent CN218917529U discloses a load box, which consists of a housing, a cooling plate and a resistor group, wherein the cooling plate is arranged in the housing. The cooling plate is used to support and cool the resistor group. The resistor group is arranged on the cooling plate. The resistor group includes a plurality of resistors, which are connected in parallel through a metal bar. This design helps to reduce the number of structural parts in the load box, simplify the structure of the load box, and facilitate the assembly and disassembly of the load box.

[0004] There are still several problems with the above documents: the spacing of the cooling plate cannot be adjusted and cannot cope with resistor components of different sizes; the heat dissipation effect is limited, and heat accumulation affects the load effect. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figures 1 to 8 As shown, an air conditioning load box includes a front box body 1, a fixing frame 6, a rear box body 7 and an air pump 8. The front box body 1 includes a tray 2, a shutter 3, a bracket 4 and a positioning groove 5. The front box body 1 is fitted with the rear box body 7 and is internally connected. Several fixing frames 6 are arranged up and down and installed in the front box body 1. The air pump 8 is installed in the rear box body 7 and is at the bottom of the rear box body 7. The tray 2 is installed in the fixing frame 6, the shutter 3 is installed on both sides of the front box body 1, the bracket 4 is installed at the four corners of the front box body 1, and the positioning groove 5 is set on the bracket 4.

[0028] The device installs each resistance element through the tray 2, and then connects the power cord passing through the rear box 7 to the tray 2 to form a load test. The fixing frame 6 installs the tray 2 in the front box 1. The rear box 7 is used to provide positioning for installing the air pump 8. The air pump 8 is used to accelerate the cooling of the heat generated by the resistance elements on the tray 2. The bracket 4 and the positioning groove 5 are used to adjust the installation quantity and installation position of the fixing frame 6 to ensure that a certain number of trays 2 are installed according to actual needs, so that the gaps between multiple trays 2 can adapt to resistance elements of different sizes. The shutter 3 is used to assist the heat dissipation of the tray 2 and reduce the entry of dust.

[0029] See also Figure 3 to Figure 5 As shown, the tray 2 includes a ventilation duct 21 , ventilation holes 22 and positioning holes 23 . The ventilation duct 21 is arranged in a surrounding manner in the tray 2 . The ventilation holes 22 are distributed in an array on the surface of the tray 2 . The positioning holes 23 are installed on both sides of the tray 2 .

[0030] The air holes 22 are used to reduce the contact between the bottom of the resistor element and the upper surface of the tray 2, thereby improving the heat dissipation effect of the resistor element and facilitating the positioning of the resistor element for installation. The air duct 21 is connected to the air pump 8. In order to avoid water leakage and damage to the electronic components when using water cooling, air cooling is used. The air pump 8 sends cold air into the air duct 21, absorbs part of the heat on the tray 2, and then discharges the heat by the air pump 8. The positioning holes 23 are used to prevent the air pump 8 from blowing the tray 2 away from the fixing frame 6 when blowing air.

[0031] See also Figures 1 to 8 As shown, the shutter 3 includes window blades 31 and a rotating shaft 32 . The window blades 31 are arranged in an array at the center of the shutter 3 . The rotating shaft 32 passes through the window blades 31 and is installed on the shutter 3 and forms a rotation connection with the window blades 31 .

[0032] The window blades 31 can be rotated on the shutters 3 through the shaft 32 to adjust the ventilation capacity of the shutters 3. When the load box is stationary, the shutters 3 fall down to close the front box body 1, preventing a large amount of floating dust and falling dust from entering the front box body 1 and affecting the operation of electronic components, thereby ensuring the accuracy of the load test.

[0033] See also Figure 8 As shown, the window vane 31 includes a connecting rod 311 and a push rod 312 . The connecting rod 311 passes through one side of the window vane 31 , and the push rod 312 fixes the connecting rod 311 on each window vane 31 .

[0034] The connecting rod 311 is rotatably connected to the window blade 31 . By pushing the connecting rod 311 up and down, the rotation angle of the window blade 31 on the rotating shaft 32 is adjusted, so that the size of the opening of the shutter 3 can be adjusted according to actual needs.

[0035] See also Figure 3 to Figure 6As shown, the fixed frame 6 includes a baffle 61, a pulley 62, a slide groove 63 and a fixed plate 64. The baffle 61 is horizontally arranged on the fixed frame 6 and is located in front of the air pump 8. The slide groove 63 is arranged on both sides of the fixed frame 6. The pulley 62 is installed in the slide groove 63. The fixed plate 64 is installed on both sides of the fixed frame 6 and corresponds to the position of the positioning groove 5.

[0036] The baffle 61 is used to provide positioning for the connection between the tray 2 and the air pump 8. The tray 2 forms a sliding connection with the fixed frame 6. The pulley 62 is used to reduce the friction generated when the tray 2 slides to increase the service life of the tray 2 and the fixed frame 6. At the same time, the sliding of the tray 2 on the fixed frame 6 can ensure the rapid replacement of the electronic components on the tray 2 to perform different load tests. The fixing plate 64 is used to connect the fixed frame 6 to the bracket 4.

[0037] See also Figure 4 to Figure 7 As shown, the baffle 61 includes a joint 611, a wiring 612 and a threaded hole 613. The threaded hole 613 is set on the baffle 61, and the joint 611 is installed in the threaded hole 613. One end of the wiring 612 is connected to the bottom of the joint 611, and the other end is connected to the air pump 8.

[0038] The connector 611 is rotatably connected in the threaded hole 613 to ensure that the connector 611 and the baffle 61 are securely installed. When the tray 2 is installed on the fixing frame 6 via the slide groove 63, the connector 611 is inserted into the side of the tray 2 and circulates air into the tray 2 through the connection 612 and the connection with the air pump 8 to accelerate the heat dissipation of the tray 2.

[0039] See also Figure 6 As shown, the fixing plate 64 includes a positioning bar 641, a screw 642 and a nut 643. The positioning bar 641 corresponds to the position of the positioning slot 5.
