TECHNICAL FIELD

[0001] The present application relates to the technical field of blasting, in particular to a medicine injection device for static blasting. BACKGROUND

[0002] At present, the foundation of civil buildings is mostly made of high-strength concrete, which has high compressive strength and durability. However, when demolishing old buildings, the traditional cannon machine demolition method is inefficient, time-consuming, and has a great impact on the surrounding environment. Therefore, in recent years, the method of static blasting has been increasingly used to improve the demolition efficiency and reduce environmental pollution. The core of static blasting is to inject expanding agent into the concrete, which generates pressure in the chemical reaction, causing the concrete to crack. This method not only improves the construction efficiency, but also reduces noise and dust pollution, and has been widely applied and developed.

[0003] There are two solutions in the prior art, manual medicine injection method: workers pour the prepared expanding agent into small holes and then use manual tools to compact it. This method is simple to operate, but inefficient, prone to waste of medicine, and labor-intensive. Automatic medicine injection equipment: some construction units have begun to use automatic medicine injection equipment. These devices can accurately control the amount of medicine injection, but still have high cost and complex maintenance problems. In addition, due to the large size of the equipment, it is not convenient to operate in a small space.

[0004] Both manual medicine injection and automatic medicine injection equipment have obvious shortcomings. Manual medicine injection is simple, but prone to medicine overflow during actual operation, not only wasting a lot of resources, but also increasing the workload of on-site cleaning. Although automatic medicine injection equipment can improve accuracy and efficiency, its high cost and complex maintenance requirements make it difficult for small and medium-sized construction units to bear. In addition, the operation flexibility of such large equipment is poor and cannot adapt to various construction conditions. Therefore, there is an urgent need for a medicine injection device for static blasting. SUMMARY

[0008] Preferably, an inside of the main shell is provided with an observation port, an inside of the observation port is fixedly connected with a glass plate, the glass plate is matched with the medicine storage tank, a surface of the glass plate is engraved with a scale line.

[0009] Preferably, the medicine delivery pipe adopts a PVC hose, a length of the medicine delivery pipe is 2 m, an inner diameter of the medicine delivery pipe is 6 mm, an output port of the medicine delivery pipe is fixedly connected with a injection head, the injection head adopts a stainless steel material, a length of the injection head is 100 mm, an outer diameter of the injection head is 10 mm, a front end of the injection head is provided with a nozzle, a caliber of the front end nozzle is 2 mm.

[0010] Preferably, the main shell adopts an aluminum alloy material, a size specification of the main shell is a diameter of 150 mm and a height of 400 mm, the hand pump adopts a cast iron material, a maximum stroke of the hand pump is 10 cm, and a compressible frequency of the hand pump per minute is 60 times.

[0011] Preferably, the medicine storage tank adopts a transparent plastic material, a capacity of the medicine storage tank is 5 L, an outer surface of the medicine storage tank is matched with the scale line on the surface of the glass plate.

[0012] Preferably, a bottom of the water pumping pipe is movably penetrated into an inside of the main shell and extended to a bottom of the main shell, the water pumping pipe is matched with the hand pump.

[0013] Preferably, the automatic measurement module further comprises a pressure sensor, a flow sensor and a control panel, the pressure sensor is integrated at a front end of the injection head, the pressure sensor monitors a pressure in a hole in real time, and transmits a signal to the control panel, the flow sensor is installed in an inside of the medicine delivery pipe, the flow sensor monitors a flow of medicine in the pipe in real time, and transmits a signal to the control panel.

[0014] Preferably, the control panel includes a wireless port and an alarm. The control panel is electrically connected to the electric valve. Pressure thresholds and flow thresholds are preset through the control panel. The alarm and pressure sensor are electrically connected.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: Firstly, in the operation of this invention, the prepared expanding agent is first poured into the storage tank, and the lid is closed. Then, holding the handle of the main housing, the tip of the injection head is inserted into the pre-drilled concrete hole. Next, the handle of the manual pump is repeatedly pressed, pushing the piston downwards and sending the agent in the storage tank through the delivery tube into the injection head, and finally injecting it into the concrete hole. As the agent is continuously injected, the pressure at the front of the injection head gradually increases, ensuring that the agent is evenly distributed throughout the hole. When the agent is completely injected, the manual pump is released, the injection head is pulled out, and one injection operation is completed. The storage tank is made of transparent plastic. When the storage tank is fixed to the main housing via a flange, the main housing secures and protects the storage tank. This design ensures that the medicine storage tank and the glass plate are of equal size and correspond in position, allowing the graduations on the glass plate to align with the medicine storage tank. This facilitates real-time monitoring of the dosage during injection and inspection of any residue inside the storage tank during subsequent cleaning. The injection mechanism significantly improves injection efficiency, shortens the construction cycle, and reduces project costs. The alignment of the graduations and the manual operation of the pump effectively reduce drug waste, conserve resources, and alleviate environmental pressure. Furthermore, it simplifies the operation process, reduces the labor intensity of workers, and improves construction safety. Its compact and portable design allows for flexible operation in confined spaces, expanding its applicability. It can be freely moved using handles and feet.

[0016] Secondly, this invention involves cleaning and maintaining the equipment. The manual pump is operated to move the piston upwards, drawing out the medication delivery pipe to determine if any medication residue remains inside. During cleaning, clean water from the tank flows through the clean water pipe and is naturally pressed against the electric valve by gravity. Opening the electric valve connects the clean water pipe and the suction pipe. The vertically upward suction pipe prevents water from directly entering the storage tank. Instead, the low-pressure air generated when the manual pump is operated simultaneously draws out both the medication delivery pipe and the clean water pipe, removing any remaining medication from the delivery pipe. The medicine and clean water from the pump pipe are drawn out together and collected in the storage tank. Then, the staff pours out the mixed liquid in the storage tank and repeats the process several times. After rinsing with clean water, the storage tank is quickly cleaned, preventing residue from clogging the pipes. The cleaning mechanism can quickly draw and extract water using the pre-installed manual pump, making it easier to clean and further enhancing its compact and portable performance. It can be cleaned immediately after the work is completed without having to find a water source or fill it.

[0017] Third, this invention integrates a pressure sensor at the front end of the injection head via an automatic measurement module to monitor the pressure inside the orifice in real time. During preparation, the pressure threshold is adjusted according to different orifice diameters. As the agent is continuously injected, the pressure at the front of the injection head gradually increases. When the pressure exceeds the set threshold, it indicates that the agent is evenly distributed throughout the orifice, or that a blockage has occurred inside the delivery tube. This immediately triggers an alarm to the operator. The alarm includes an LED indicator or a buzzer, respectively installed on the control panel. The control panel uses a programmable logic controller (PLC) control panel, model Siemens S7-200, which is powerful and flexible in programming, allowing operators to manually adjust and set the threshold. A flow sensor detects the actual flow rate through the delivery tube; adjusting the flow threshold according to different orifice diameters also includes adjusting the flow rate threshold. Different settings are configured according to the actual blasting needs. The threshold, used in conjunction with a pressure sensor, allows the flow sensor to detect the corresponding flow rate as the medication is continuously injected. If the flow rate threshold is exceeded while the pressure threshold is not, it indicates an error in the orifice size determination. Sufficient medication may not be evenly distributed throughout the orifice, resulting in pressure not reaching the expected standard and failing to trigger the threshold. Other possibilities include leaks in the delivery tubing or injection head, or a faulty pressure sensor failing to correctly identify the actual flow rate, leading to an incorrect flow rate threshold determination. This also triggers an alarm, prompting maintenance. Simultaneously, the control panel automatically closes and disables the electric valve to prevent water loss during disassembly, which could cause the storage tank to open and release internal pressure, creating suction on the pumping pipe. The automatic measurement module improves equipment safety, increases injection accuracy, reduces manual inspection time, and allows for quick identification of the problem.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the present invention provides a technical solution: a static blasting injection device, including an injection mechanism 1, a cleaning mechanism 2 is provided at the bottom of the injection mechanism 1, and the outer side of the cleaning mechanism 2 is fixedly connected to the injection mechanism 1. The drug dispensing mechanism 1 includes a main housing 101, inside which is a drug storage tank 102. The top of the drug storage tank 102 is covered with a lid 103. A manual pump 104 is installed on the outside of the main housing 101. A handle 105 is installed on the outside of the manual pump 104. A piston rod 106 is fixedly connected to the top of the manual pump 104. The output port of the piston rod 106 is fixedly connected to the inside of the drug storage tank 102. A piston is built into the drug storage tank 102. The piston rod 106 is fixedly connected to the piston. A drug delivery tube 111 is fixedly connected to the bottom of the drug storage tank 102. A handle 107 is fixedly connected to the outside of the main housing 101.

[0021] The bottom of the main shell 101 is fixedly connected with a support leg 108. Multiple support legs 108 are provided and arranged in a circular array around the medicine storage tank 102. A flange 110 is installed on the top of the inner wall of the main shell 101, and the top of the flange 110 is installed with the medicine storage tank 102.

[0022] An observation port is provided inside the main housing 101, and a glass plate 109 is fixedly connected inside the observation port. The glass plate 109 is adapted to the medicine storage tank 102, and scale lines are engraved on the surface of the glass plate 109.

[0023] The infusion tube 111 is made of PVC hose, with a length of 2m and an inner diameter of 6mm. The output port of the infusion tube 111 is fixedly connected to the injection head 112, which is made of stainless steel, with a length of 100mm and an outer diameter of 10mm. The front end is equipped with a nozzle with a nozzle diameter of 2mm.

[0024] The main housing 101 is made of aluminum alloy and has a diameter of 150mm and a height of 400mm. The manual pump 104 is made of cast iron, with a maximum stroke of 10cm and a compression rate of 60 times per minute.

[0025] The medicine storage container 102 is made of transparent plastic and has a capacity of 5L. The outer surface of the medicine storage container 102 is compatible with the scale lines on the surface of the glass plate 109.

[0026] Through the above technical solution, during the working process, firstly, the prepared expanding agent is poured into the storage tank 102, and the lid 103 is closed. Then, holding the handle 107 of the main housing 101, the tip of the injection head 112 is inserted into the pre-drilled concrete hole. Next, the handle 105 of the manual pump 104 is repeatedly pressed to push the piston downward, sending the agent in the storage tank 102 into the injection head 112 through the delivery pipe 111, and finally injecting it into the concrete hole. As the agent is continuously injected, the pressure at the front of the injection head gradually increases to ensure that the agent is evenly distributed throughout the hole. When the agent is completely injected, the manual pump 104 is released, and the injection head 112 is pulled out, completing one injection operation. The storage tank 102 is made of transparent plastic. When the storage tank 102 is fixed to the main housing 101 by the flange 110, the main housing 101... The medicine storage tank 102 is fixed and protected, and the medicine storage tank 102 and the glass plate 109 are of the same size and correspond to each other. The scale lines engraved on the glass plate 109 can correspond to the medicine storage tank 102, which makes it convenient for the staff to check the amount of medicine in real time during the injection, or to check whether there is any residue inside the medicine storage tank 102 during the later cleaning work. The medicine injection mechanism 1 significantly improves the injection efficiency, shortens the construction cycle, and reduces the project cost. The correspondence of the scale and the manual operation of the manual pump 104 effectively reduce the waste of medicine, save resources, reduce environmental pressure, simplify the operation process, reduce the labor intensity of workers, and improve construction safety. Its compact and portable design allows the device to be operated flexibly in narrow spaces, expanding the scope of application. Its position can be moved freely by the handle 107 and the support leg 108.

[0027] Example 2 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the present invention provides a technical solution: a static blasting injection device, wherein the cleaning mechanism 2 includes a water tank 201, the water tank 201 is fixedly connected to the main housing 101, the top of the water tank 201 is fixedly connected to a water inlet 202, the bottom of the water tank 201 is fixedly connected to a clean water pipe 203, the bottom of the storage tank 102 is fixedly connected to a water suction pipe 205, the bottom of the water suction pipe 205 is fixedly connected to an electric valve 204, and the electric valve 204 is fixedly connected to the clean water pipe 203.

[0028] The bottom of the water pump 205 extends through the interior of the main housing 101 and to its bottom, and the water pump 205 is adapted to the manual pump 104.

[0029] Using the above technical solution, after the work is completed, the equipment is cleaned and maintained. The manual pump 104 is activated to move the piston upwards, drawing fluid from the delivery pipe 111 to check for any remaining medication. During cleaning, the clean water in the water tank 201 flows through the clean water pipe 203 and is naturally pressed against the electric valve 204 by gravity. Opening the electric valve 204 connects the clean water pipe 203 to the suction pipe 205. The vertically upward suction pipe 205 prevents the liquid from directly entering the storage tank 102. Instead, when the manual pump 104 is activated, the low-pressure air generated simultaneously cleans the delivery pipe 111 and the clean water pipe 203. The extraction process involves drawing out any residual medicine from the infusion tube 111 and the clean water from the water extraction tube 205, allowing it to collect in the storage tank 102. Then, staff pour out the mixture from the storage tank 102. This process is repeated several times, followed by rinsing with clean water, quickly cleaning the storage tank 102 and preventing residue from clogging the pipes. The cleaning mechanism 2 utilizes the pre-installed manual pump 104 to quickly draw and extract water, making cleaning easier and further enhancing its compact and portable design. Cleaning can be performed immediately after work, eliminating the need to search for a water source or refill the tank.

[0030] Example 3 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the present invention provides a technical solution: a static blasting injection device, which further includes an automatic measurement module. The automatic measurement module includes a pressure sensor, a flow sensor and a control panel. The pressure sensor is integrated at the front end of the injection head 112 to monitor the pressure inside the hole in real time and transmit the signal to the control panel. The flow sensor is installed inside the delivery tube 111 to monitor the flow rate of the drug in the tube in real time and transmit the signal to the control panel.

[0031] The control panel includes a wireless port, an alarm, and is electrically connected to the electric valve 204. Pressure and flow thresholds are preset via the control panel, and the alarm and pressure sensor are electrically connected.

[0032] Through the above technical solution, an automatic measurement module integrates a pressure sensor at the front end of the injection head 112 to monitor the pressure inside the hole in real time. During preparation, the pressure threshold is adjusted according to different hole diameters. As the agent is continuously injected, the pressure at the front of the injection head 112 gradually increases. When the pressure exceeds the set threshold, it indicates that the agent is evenly distributed throughout the hole, or that a blockage has occurred inside the delivery tube 111. In this case, an alarm is immediately triggered to alert the operator. The alarm includes an LED indicator or a buzzer, respectively installed on the control panel. The control panel uses a programmable logic controller (PLC) control panel, model Siemens S7-200, which is powerful and flexible in programming, allowing operators to manually adjust and set the threshold. A flow sensor is used to detect the actual flow rate through the delivery tube 111. Adjusting the flow rate threshold according to different hole diameters also includes adjusting the flow rate threshold, which is set according to the actual blasting needs. The threshold, used in conjunction with a pressure sensor, allows the flow sensor to detect the corresponding flow rate as the medication is continuously injected. If the flow rate threshold is exceeded while the pressure threshold is not, it indicates an error in the orifice size determination. Sufficient medication may not be evenly distributed throughout the orifice, resulting in pressure not reaching the expected standard and failing to trigger the threshold. Alternatively, it could be due to leakage from the infusion tube 111 or injection head 112, or a malfunctioning pressure sensor that fails to correctly identify the actual flow rate, leading to an incorrect flow rate threshold determination. This also triggers an alarm, prompting maintenance. Simultaneously, the control panel automatically closes and disables the electric valve 204 to prevent the storage tank 102 from opening during disassembly for maintenance, which could release internal pressure and create suction on the water pipe 205, causing water loss. The automatic measurement module improves equipment safety, increases injection accuracy, reduces manual inspection time, and allows for rapid identification of the problem.

[0033] During use, the prepared expanding agent is first poured into the storage tank 102, and the lid 103 is closed. Then, holding the handle 107 of the main housing 101, the tip of the injection head 112 is inserted into the pre-drilled concrete hole. Next, the handle 105 of the manual pump 104 is repeatedly pressed to push the piston downward, sending the agent in the storage tank 102 into the injection head 112 through the delivery tube 111, and finally injecting it into the concrete hole.

Its compact and portable design allows the device to be operated flexibly in narrow spaces, expanding the scope of application. Its position can be moved freely by the handle 107 and the support leg 108. To clean and maintain the equipment, manually operate pump 104 to move the piston upwards, drawing out the medicine delivery pipe 111 to check for any remaining medicine. During cleaning, the purified water in water tank 201 will naturally press against electric valve 204 due to gravity through purified water pipe 203. Open electric valve 204 to connect purified water pipe 203 with water suction pipe 205. The vertically upward suction pipe 205 prevents the liquid from directly entering the medicine storage tank 102. Instead, when manual pump 104 is operated, the low air pressure generated simultaneously draws out the medicine delivery pipe 111 and purified water pipe 203. The remaining liquid medicine inside the 11th tank is extracted along with the clean water in the water pipe 205, and collected in the medicine storage tank 102. Then, the staff pours out the mixed liquid in the medicine storage tank 102, and after repeated extraction and rinsing with clean water, the medicine storage tank 102 can be cleaned quickly, preventing residue from clogging the pipe. Through the cleaning mechanism 2, the water can be quickly drawn and extracted by the existing manual pump 104, which is more convenient for cleaning and further improves its compact and portable performance. It can be cleaned immediately after the work is completed without having to find a water source or fill it.An automatic measurement module integrates a pressure sensor at the front end of the injection head 112 to monitor the pressure inside the hole in real time.
