Description

Technical Field

[0001] This utility model relates to the field of enclosed busbar technology, specifically to an intelligent expansion joint structure for a common-enclosure enclosed busbar. Background Technology

[0002] The expansion joint structure is a compensation device with expansion capability installed at an appropriate position on the common enclosure busbar section during the on-site installation of the common enclosure busbar. It is designed to eliminate positional deviations between busbars caused by excessively long straight busbars, uneven settlement of the supporting foundation, or increased internal stress due to thermal expansion and contraction of the enclosure busbar, so as to achieve adjustment in both horizontal and vertical directions.

[0003] However, existing expansion joints still have shortcomings, specifically: the expansion structure of existing expansion joints is made of rubber, which is prone to aging after long-term use, and replacing the expansion joints is relatively difficult. Utility Model Content

[0004] The purpose of this invention is to provide a smart expansion joint structure for a common-enclosed busbar to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A common-enclosed busbar intelligent expansion joint structure includes an expansion joint body. The outer surface of the expansion joint body is provided with a connecting mechanism for installing and fixing the expansion joint body. The outer wall of the connecting mechanism is slidably connected to a mounting base. An electronic button is installed on the outer wall of the mounting base, and a terminal block is installed on the top of the mounting base.

[0007] As a preferred embodiment of this utility model, the connecting mechanism includes a connecting plate fixedly connected to the outer wall of the telescopic joint body. A positioning pin is fixedly connected to the outer wall of the connecting plate. A locking block is slidably connected to the outer wall of the positioning pin and within the mounting base. An adjusting ring is fixedly connected to the outer wall of the locking block and within the mounting base. An adjusting gear is fixedly connected to the outer surface of the adjusting ring and on the side away from the locking block. A sliding rack is slidably connected to the outer surface of the adjusting gear and above and below the connecting plate. A piston rod is fixedly connected to the outer wall of the sliding rack and at the end away from the adjusting gear. A fixing sleeve is slidably connected to the outer wall of the piston rod. A miniature air pump is fixedly connected to the outer wall of the fixing sleeve. A return spring is fixedly connected to the outer wall of the piston rod.

[0008] As a preferred embodiment of this utility model, the expansion joint body is made of rubber corrugated pipe, and two sets of mounting bases and connecting mechanisms are provided. The mounting base has a T-shaped structure design.

[0009] As a preferred embodiment of this utility model, the mounting base is made of aluminum alloy, and multiple sets of mounting slots are formed on the outer wall of the mounting base. The connection method between the terminal block and the electronic button is electrical connection.

[0010] As a preferred embodiment of this utility model, the connecting plate, positioning pin, locking block, and adjusting ring are all made of stainless steel. Multiple sets of positioning pins and locking blocks are provided. The positioning pins penetrate and extend into the mounting base. The connection between the reset spring and the fixing sleeve, and between the fixing sleeve and the mounting base, are all fixed connections.

[0011] As a preferred embodiment of this utility model, the piston rod is made of ABS plastic, and two sets of piston rod, fixed sleeve, micro air pump and sliding rack are provided. The outer surface of the mounting base is provided with a groove at the corresponding position of the micro air pump, and a dustproof net is fixedly connected in the groove. The sliding rack is connected to the mounting base by sliding connection.

[0012] Through the above technical solution, the dustproof net can prevent dust in the air from clogging the miniature air pump.

[0013] As a preferred embodiment of this utility model, the piston rod has a T-shaped structure design, a rubber sealing gasket is fixedly connected to the outer surface of the connecting plate near the mounting base, a slot is provided on the outer surface of the positioning pin at the corresponding position of the locking block, and the connection between the micro air pump and the electronic button is an electrical connection.

[0014] Through the above technical solution, the rubber sealing ring can block the gap between the connecting plate and the mounting base, preventing foreign objects from entering the mounting base and the body of the expansion joint.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, an intelligent expansion joint structure for a common-enclosed busbar is provided. The expansion joint body is installed using the connecting mechanism in the device, and the mounting base is fixed on the enclosed busbar. When the expansion joint body ages, the terminal block is connected to an external power source using a wire. Pressing the electronic button activates a micro air pump, which sends outside air into the fixed sleeve. The air entering the fixed sleeve pushes the piston rod outward. The outward-moving piston rod drives the sliding rack, which in turn drives the adjusting gear to rotate. The rotating adjusting gear drives the locking block to rotate through the adjusting ring. The rotating locking block disengages from the positioning pin, and the locking block no longer holds the positioning pin. Pulling the connecting plate causes the positioning pin to move outward and detach from the mounting base, thus removing the expansion joint body. The disassembly operation is relatively convenient, solving the problem that existing expansion joints, whose expansion structure is made of rubber, are prone to aging after long-term use, making replacement difficult.

On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and complete.

[0024] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0025] A common-enclosed busbar intelligent expansion joint structure includes an expansion joint body 1. A connecting mechanism 2 is provided on the outer surface of the expansion joint body 1 for installing and fixing the expansion joint body 1. A mounting base 3 is slidably connected to the outer wall of the connecting mechanism 2. An electronic button 4 is installed on the outer wall of the mounting base 3. A terminal block 5 is installed on the top of the mounting base 3.

[0026] The expansion joint body 1 is made of rubber bellows, and there are two sets of mounting base 3 and connecting mechanism 2. The mounting base 3 is a T-shaped structure design.

[0027] The mounting base 3 is made of aluminum alloy, and multiple sets of mounting slots are opened on the outer wall of the mounting base 3. The connection between the terminal block 5 and the electronic button 4 is electrical.

[0028] In this embodiment, reference Figure 2 , Figure 3 as well as Figure 4 The connecting mechanism 2 includes a connecting plate 201 fixedly connected to the outer wall of the telescopic joint body 1. A positioning pin 202 is fixedly connected to the outer wall of the connecting plate 201. A locking block 203 is slidably connected to the outer wall of the positioning pin 202 and inside the mounting base 3. An adjusting ring 204 is fixedly connected to the outer wall of the locking block 203 and inside the mounting base 3. An adjusting gear 205 is fixedly connected to the outer surface of the adjusting ring 204 and on the side away from the locking block 203. A sliding rack 206 is slidably connected to the outer surface of the adjusting gear 205 and above and below the connecting plate 201. A piston rod 207 is fixedly connected to the outer wall of the sliding rack 206 and at the end away from the adjusting gear 205. A fixing sleeve 208 is slidably connected to the outer wall of the piston rod 207. A micro air pump 209 is fixedly connected to the outer wall of the fixing sleeve 208. A return spring 210 is fixedly connected to the outer wall of the piston rod 207.

[0029] The connecting plate 201, positioning pin 202, locking block 203 and adjusting ring 204 are all made of stainless steel. Multiple sets of positioning pin 202 and locking block 203 are provided. Positioning pin 202 passes through and extends into the mounting base 3. The connection between the return spring 210 and the fixing sleeve 208 and the fixing sleeve 208 and the mounting base 3 are all fixed connections.

[0030] The piston rod 207 is made of ABS plastic. Two sets of piston rod 207, fixed sleeve 208, micro air pump 209 and sliding rack 206 are provided. The outer surface of the mounting base 3 is provided with a groove at the corresponding position of the micro air pump 209, and a dustproof net is fixedly connected in the groove. The dustproof net can prevent dust in the air from clogging the micro air pump 209. The sliding rack 206 is connected to the mounting base 3 by sliding connection.

[0031] The piston rod 207 has a T-shaped structure design. A rubber sealing gasket is fixedly connected to the outer surface of the connecting plate 201 and the side near the mounting base 3. The rubber sealing ring can block the gap between the connecting plate 201 and the mounting base 3 to prevent foreign objects from entering the mounting base 3 and the telescopic joint body 1. A slot is opened on the outer surface of the positioning pin 202 at the corresponding position of the locking block 203. The micro air pump 209 is connected to the electronic button 4 by electrical connection.

[0032] The working process of this utility model is as follows: When using the intelligent expansion joint structure for a shared-enclosed busbar designed in this scheme, the mounting base 3 is fixed to the enclosed busbar. When the expansion joint body 1 ages, the terminal block 5 is connected to an external power source using a wire. Pressing the electronic button 4 activates the micro air pump 209, which sends outside air into the fixed sleeve 208. The air entering the fixed sleeve 208 pushes the piston rod 207 outward. The outward-moving piston rod 207 drives the sliding rack 206, which in turn drives the adjusting gear 205 to rotate. The rotating adjusting gear 205, through the adjusting ring 204, drives the locking block 203 to rotate. The rotating locking block 203 disengages from the positioning pin 202, and no longer holds the positioning pin 202, thus pulling the connecting plate 201. The connecting plate 201 drives the positioning pin 202 to move outward and disengage from the mounting base 3, thereby removing the telescopic joint body 1. The new telescopic joint body 1 is then installed on the connecting plate 201, and the connecting plate 201 is placed on the mounting base 3. The positioning pin 202 is reinserted into the mounting base 3. The micro air pump 209 draws outside air out of the fixed sleeve 208. The return spring 210 pulls the piston rod 207 inward. The inwardly moving piston rod 207 drives the sliding rack 206 to move in the opposite direction. The inwardly sliding sliding rack 206 drives the adjusting gear 205 to rotate in the opposite direction. The reversely rotating adjusting gear 205 drives the locking block 203 to rotate in the opposite direction through the adjusting ring 204. The reversely rotating locking block 203 reinsertes the positioning pin 202, and the locking block 203 locks the positioning pin 202, thereby fixing the telescopic joint body 1 onto the mounting base 3.

[0033] The electronic button 4, terminal 5, and miniature air pump 209 used in this utility model are all existing known electrical devices, and all can be purchased and used directly on the market. Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the electronic button 4, terminal 5, and miniature air pump 209 will not be described in detail here.
