Description

Technical Field

[0001] The present invention relates to the field of auxiliary equipment for photovoltaic support pile foundation construction, and in particular to auxiliary equipment for photovoltaic support pile foundation construction. Background Art

[0002] Some photovoltaic power generation equipment are large in size and weight. Simply fixing the bracket on the ground cannot cope with the impact of environmental disasters such as strong winds and heavy rains in open outdoor environments. Therefore, it is necessary to carry out pile foundation fixing construction on the photovoltaic bracket. After the pile foundation is poured, the pile foundation is like a cement pillar protruding from the ground. It is necessary to drill some corresponding bottom holes on the top of the pile foundation. After cooperating with the bracket, the bracket and the photovoltaic equipment on the bracket are fixed on the pile foundation.

[0003] When drilling holes in cement materials, a handheld electric drill is generally used to simply drill to a certain depth. However, it costs a lot to complete the pouring of the pile foundation. When drilling with a handheld electric drill, since the entire process relies on limbs and experience, there is no guarantee that the drilling position will not be biased. During the descent of the handheld drill, the drilling path is likely to be skewed accidentally, affecting the subsequent installation of the photovoltaic bracket. In addition, when drilling holes in the cement pile foundation, the dust generated by the drill bit will float around above the pile foundation as the drill bit rotates at high speed. The dust drilled by the drill bit is fine, and people can easily cause physical harm by breathing it at close range. Sometimes, water is sprayed while drilling to reduce dust. The water flow cannot completely contact the dust in the air, and the falling water flow forms mud, which flows on the pile foundation, making it very dirty and affecting the operation of the construction personnel, and wastes water. Therefore, an auxiliary equipment for the pile foundation construction of photovoltaic brackets that is convenient for pile foundation drills is needed. Summary of the invention

[0029] The present invention provides the following embodiments

[0030] Example 1

[0031] The embodiment of the present invention provides a hybrid heating and heat supply device, such as Figure 1-4 As shown, an auxiliary device for photovoltaic support pile foundation construction includes: a base 1, and a control button 17 is connected to the top of the base 1 for controlling the device to perform corresponding operations.

[0032] The base 1 is connected to a device compartment 19, and the device compartment 19 is downwardly connected to an electric telescopic rod 11 for driving a drill bit 14 to move up and down, so that the high-speed rotating drill bit 14 can be used to drill into the pile foundation. The moving end of the electric telescopic rod 11 is downwardly connected to a machine box 12 for placing a motor 13. The machine box 12 is connected to a motor 13 that cooperates with a transmission shaft 20 to provide power for the rotation of the transmission shaft 20. The machine box 12 is connected to a transmission shaft 20 that rotates downward at one end away from the base 1 to drive the drill bit 14 to rotate at a high speed. The bottom end of the transmission shaft 20 is connected to a drill bit 14 for drilling a bottom hole suitable for connecting a photovoltaic support frame 18 at the top of the pile foundation.

[0033] The base 1 is located outside the device bin 19 and is connected to a water tank 2 to provide a water source for the atomizing nozzle 9. A water pipe 6 is connected to one side of the water tank 2. A water pump 10 is connected to the water pipe 6 to transport the water in the water tank 2 to the atomizing nozzle 9 through the water pipe 6. A branch pipe 8 is connected to both sides of the drill bit 14 to facilitate the establishment of the atomizing nozzle 9 on both sides of the drill bit 14 for dust removal. A three-way pipe 7 is connected between the water pipe 6 and the branch pipe 8 at one end away from the drill bit 14 to transfer the water in the water pipe 6 to the atomizing nozzle 9. The water flows into the branch pipes 8 on both sides. The bottom end of the branch pipes 8 is connected with an atomizing nozzle 9 matched with the drill bit 14, which is used to atomize the water and spray it toward the hole drilled by the drill bit 14 to facilitate dust removal. The top side of the base 1 is connected with a water inlet 3 connected to the water tank 2, which is used to replenish water in the water tank 2. The base 1 is connected with a box cover 4 matched with the water inlet 3 on one side, which is used to close or open the water inlet 3. The top of the water tank 2 is connected with a liquid level sensor 5 away from the water inlet 3 to monitor the water volume in the water tank 2.

[0034] The bottom of the electric telescopic rod 11 is connected outwardly with a support frame 18 that cooperates with the branch pipe 8, which is used to support the auxiliary structure around the drill bit 14. The top of the support frame 18 is connected with a transparent baffle 15 that cooperates with the atomizing nozzle 9, which is used to prevent the drill bit 14 from drilling holes in the pile foundation and splashing dust, mud, etc. to the outside. The bottom end of the transparent baffle 15 is connected with a positioning plate 16 that cooperates with the drill bit 14, which is used to make the lower hole of the drill bit 14 and the drilling path perpendicular to the top surface of the pile foundation.

[0035] In the specific implementation of the present invention, the device is used to assist in the construction of the photovoltaic support pile foundation. When drilling the pile foundation, the base 1 of the device is held by hand, and the drill bit 14 is aligned with the corresponding drilling position. The device is slightly pressed on the top of the pile foundation so that the positioning plate 16 at the bottom of the device fits with the top surface of the pile foundation, thereby indirectly finding and fixing the vertical position between the drill hole 14 and the upper surface of the pile foundation, avoiding the deviation of the drill hole, which causes problems in the subsequent photovoltaic support installation. The device is started by the corresponding control button 17 on the top of the base 1, and the motor 13 drives the drill bit 14 to rotate at a high speed above the pile foundation, and the electric extension The retracted rod 11 pushes the high-speed rotating drill bit 14 downward, contacts the pile foundation and continues drilling. While the drill bit 14 is drilling, the water pipe 6 continuously transports the water in the water tank 2 of the base 1 to the atomizing nozzles 9 on both sides of the drilling hole. The atomizing nozzles 9 spray the water in an atomized form. The water mist fully contacts the dust raised by the drilling hole and slowly falls down with the dust, so that the drilling process will not be filled with smoke and dust. Some mud with water may splash under the action of the high-speed rotation of the drill bit 14. The transparent baffle 15 located on the outside of the drill bit 14 can well prevent the mud from splashing to the outside, thereby preventing the mud from polluting the surrounding environment or the operator.

[0036] Example 2

[0037] On the basis of Example 1, the auxiliary equipment for photovoltaic support pile foundation construction, the drill bit 14 also includes:

[0038] A speed sensor, used to detect the rotation speed of the drill bit 14;

[0039] A controller and an alarm are electrically connected to the speed sensor and the alarm.

[0040] Optionally, the controller controls the alarm to work based on the speed sensor, comprising the following steps:

[0041] Step 1: According to formula (1) and the speed sensor detection value, calculate the thermal conductivity K of the drill bit 14 material:

[0042]

[0043] Where T is the shear temperature generated on the shear surface of the drill bit 14 on the rock per unit time (the shearing effect causes the drill bit temperature to rise during the pressing process), λ is the ratio of the friction heat generated by the drill bit 14 on the rock to the drill bit 14, J is the friction temperature generated by the friction effect during the process of the drill bit 14 pressing into the rock, resulting in the temperature rise of the drill bit 14, L is the friction length of the contact surface between the drill bit 14 and the rock, α is the thermal conductivity of the rock (the range is 0.8-1.1W / (mK)), β is the correction index of the cutting axial force of the drill bit 14 (the range is 0.34-0.58), F mis the friction between the drill bit 14 and the rock, V is the detection value of the speed sensor, Z is the cross-sectional length of the drill bit 14, and A is the top angle coefficient of the drill bit 14 (describing the proportional relationship between the angle between the two main cutting edges at the high end of the drill bit 14 and the overall diameter of the drill bit 14, with a value range of 0.03-0.22);

[0044] Step 2: According to the following formula (2), the actual output torque M of the drill bit 14 during the process of pressing into the rock is calculated. The controller compares the actual output torque M of the drill bit 14 during the process of pressing into the rock with the preset output torque range. When the actual output torque is not within the preset output torque range, the controller controls the alarm to sound an alarm:

[0045]

[0046] Wherein F is the axial force exerted on the drill bit 14, μ is the cutting torque correction index of the drill bit 14 (the value range is 0.53-0.69), β is the torsional section coefficient of the drill bit 14 (the value range is 0.22-0.91), W is the cutting torque of the drill bit 14, and χ is the tool cutting axial force correction index (the value range is 0.17-0.34).

[0047] The beneficial effects of the above technical solution are as follows: the controller controls the alarm to work based on the speed sensor, firstly calculates the thermal conductivity of the drill bit 14 material according to formula (1) and the speed sensor detection value, and comprehensively considers the shear temperature generated on the shear surface of the rock by the drill bit 14 per unit time, the drill bit temperature rise caused by the shearing action during the pressing process, the ratio of the friction heat generated by the drill bit 14 on the rock to the drill bit 14, the friction temperature generated by the friction effect during the pressing process of the drill bit 14 into the rock, the friction length of the contact surface between the drill bit 14 and the rock, the thermal conductivity of the rock, the correction index of the cutting axial force of the drill bit 14, the friction between the drill bit 14 and the rock, the cross-sectional length of the drill bit 14, and the top angle coefficient of the drill bit 14, so that the calculation result is more accurate and reliable;

[0048] Then, according to formula (2), the actual output torque of the drill bit 14 during the process of pressing into the rock is calculated, and the axial force of the drill bit 14, the cutting torque correction index of the drill bit 14, the torsional section coefficient of the drill bit 14, the cutting torque of the drill bit 14, and the tool cutting axial force correction index are comprehensively considered to make the calculation result more accurate and reliable;

[0049] The controller controls the operation of the speed sensor, and compares the actual output torque received by the drill bit 14 during the process of pressing into the rock with the preset output torque range. When the actual output torque is not within the preset output torque range, the controller controls the alarm to sound, reminding the staff to promptly inspect or replace the drill bit 14 or the drive shaft 20, thereby meeting the user's demand for auxiliary equipment for the pile foundation construction of this type of photovoltaic bracket.
