Description

Technical Field

[0001] The present application belongs to the technical field of forest fire fighting equipment, and in particular, relates to a quality inspection device dedicated to forest fire fighting water pumps. Background Art

[0002] The main difference between forest fire fighting water pumps and ordinary water pumps is that the former is more convenient and anti-collision, and has both higher head and larger flow rate. Correspondingly, the structure of forest fire fighting water pumps mainly includes pump body, external frame, and rollers. Among them, the external frame provides the carrying function and protection function, which corresponds to the above convenience and anti-collision, and the roller provides the rolling function, which corresponds to the above convenience.

[0003] On the other hand, the main test item of the above-mentioned quality inspection device is the continuous effectiveness of the pumping capacity of the water pump. Generally, under the premise of sufficient water supply, the inspection personnel continuously monitor the water output of the water pump to obtain the pumping capacity test results qualitatively or quantitatively.

[0004] For example, the Chinese utility model patent with authorization announcement number CN216695416U and authorization announcement date 2022.06.07 discloses a water pump quality inspection platform, whose structure mainly includes: a frame, a bearing seat, a sealing detection mechanism, a connecting head, and a fixing mechanism.

[0005] The water pump quality inspection platform in this utility model patent has the following advantages: when in use, the first adjusting rod is rotated to drive the two groups of movable blocks to move, thereby driving the vertical frame to adjust the distance, and then the second adjusting rod is rotated to drive the movable plate to move up and down, and the distance between the movable plate and the fixed plate is adjusted, so that water pumps of different specifications can be fixed to ensure the stability of the water pump during inspection.

[0006] However, when the quality inspection station is used to inspect forest fire water pumps, there are at least the following problems: Its fixing mechanism can only adjust the up and down and left and right installation positions of the water pump, which makes it difficult to more realistically simulate the actual use environment of the forest fire fighting water pump at the fire extinguishing scene. Therefore, the authenticity of the final continuous detection results of the water body pumping capacity is relatively low and has little reference value. Summary of the invention

[0007] The present application provides a quality inspection device dedicated to forest fire fighting water pumps, and the technical problem to be solved is: how to simulate the actual use environment of forest fire fighting water pumps during the quality inspection process, thereby improving the authenticity and reliability of the pumping capacity inspection results.

[0008] The technical solution adopted by the present application to solve the above-mentioned problem is: a quality inspection device specially used for forest fire fighting water pumps, the structure of which includes a slot-hole combination bottom plate unit, a slotted sliding plate unit which is snap-fitted on the slot-hole combination bottom plate unit and used to provide a vibration function for the frame roller, and an embedded protective frame unit which is plugged into the slot-hole combination bottom plate unit, passes through the slotted sliding plate unit, and is lifted upward to perform lateral blocking and limiting on the anti-collision frame.

[0009] A further preferred technical solution is that the slot-hole combination base plate unit includes a base plate, a rectangular mounting slot arranged on the upper surface of the base plate and used to engage the slotted sliding plate unit, and a mounting hole arranged in the rectangular mounting slot and used to plug in the embedded protective frame unit.

[0010] A further preferred technical solution is that the grooved sliding plate unit includes a sliding plate arranged on the rectangular mounting groove and used to support the frame roller, a dual-purpose slot arranged on the upper surface of the sliding plate and used to enter and exit the frame roller and accommodate the embedded protective frame unit, and a rectangular hole arranged in the dual-purpose slot and used to pass through the embedded protective frame unit.

[0011] A further preferred technical solution is that the embedded protective frame unit includes an insertion rod which is inserted into the mounting hole and passes through the rectangular hole, and a protective frame which is arranged on the insertion rod and is used to laterally block and limit the anti-collision frame.

[0012] A further preferred technical solution is that: the dual-purpose groove is U-shaped and there are two of them; the grooved sliding plate unit also includes a protruding strip arranged on the upper surface of the sliding plate and located between the two dual-purpose grooves, and used to support the anti-collision frame after the frame roller breaks.

[0013] A further preferred technical solution is that the protection frame is U-shaped, and there are two of them, and the spacing area between the two protection frames is used for the relative passage of the inlet and outlet water pipes.

[0014] A further preferred technical solution is that the grooved sliding plate unit further includes an emergency ball disposed on the upper surface of the protruding strip and used to support the anti-collision frame after the frame roller breaks.

[0015] A further preferred technical solution is that the grooved sliding plate unit further comprises a cylinder shaft connecting groove arranged on the end surface of the protruding strip and the end surface of the sliding plate.

[0016] A further preferred technical solution is that the slot-hole combination bottom plate unit also includes a connecting pipe limiting ring arranged on the bottom plate.

[0017] A further preferred technical solution is that the vertical cross-section of the protruding strip is trapezoidal.

[0018] The beneficial effects of this application include at least the following three points.

[0019] First, the quality inspection device has a simulated vibration function, which can provide a continuous vibration effect to the forest fire water pump in pumping work, simulating the bumpy action of the forest fire water pump in the actual fire fighting operation, so that the authenticity of the final water body pumping capacity continuous inspection results is better, and the credibility of the inspection data is greatly improved.

[0020] Second, the above-mentioned simulated vibration function has the advantages of simple and reliable triggering operation and water pump protection after the frame roller breaks.

[0021] Third, the forest fire fighting water pump on this device has the advantages of high stability during detection and the convenience of installing and removing the water pump before and after detection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following description is merely a preferred embodiment of the present application and does not limit the scope of the present application.

[0035] like Figure 1-Figure 10 As shown, a quality inspection device specially used for forest fire fighting water pumps comprises a slot-hole combination bottom plate unit 1, a slotted sliding plate unit 2 which is snap-fitted on the slot-hole combination bottom plate unit 1 and used to provide a vibration function to a frame roller a, and an embedded protective frame unit 3 which is plugged into the slot-hole combination bottom plate unit 1, passes through the slotted sliding plate unit 2, and is lifted upward to perform lateral blocking and limiting on an anti-collision frame b.

[0036] In this embodiment, the structure of the device also includes a cylinder 11 and a connecting pipe 12, the former is 1 or 2, and the latter is 2. One connecting pipe 12 is inserted into the detection pool f, and the water outlet of the other connecting pipe 12 is higher than the liquid level of the pool, so as to observe the effectiveness of the water pumping capacity.

[0037] The word "slot" of the slot-hole combination bottom plate unit 1 refers to its engagement with the slotted sliding plate unit 2, providing the slotted sliding plate unit 2 with a stable sliding slot structure, allowing the slotted sliding plate unit 2 to slide back and forth linearly. The word "hole" mentioned above refers to its engagement with the embedded protective frame unit 3, providing the embedded protective frame unit 3 with a horizontally fixed and vertically pluggable installation hole structure, so that: 1. When the forest fire water pump is quality inspected on the device, the former is prevented from large lateral displacement, and only vertical vibration is simulated; 2. Before and after the forest fire water pump is quality inspected on the device, the embedded protective frame unit 3 is retracted downward by "embedding", making the installation and removal of the forest fire water pump more convenient and labor-saving, without the need to move the entire device.

[0038] In addition, it should be noted that: First, the device is generally only applicable to forest fire fighting water pumps with frame rollers a. The frame rollers a repeatedly enter and move out on the grooved sliding plate unit 2, which can make the water pump vibrate up and down, simulating the actual use of forest fire fighting water pumps at the outdoor fire fighting scene as much as possible; Second, when the embedded protection frame unit 3 performs lateral blocking and limiting on the water pump, the two are not tightly fitted, and the water pump will inevitably hit the embedded protection frame unit 3, so the embedded protection frame unit 3 is made of lightweight high-strength steel; Third, the words "quality inspection" mentioned above refer to the fact that the inspection item of the device is the continuous pumping ability of the water body under the premise of repeated up and down vibration of the water pump. It is generally a qualitative inspection, which mainly inspects the motor structure stability and the sealing of various connections of the forest fire fighting water pump itself.

[0039] The slot-hole combination base plate unit 1 includes a base plate 101, a rectangular mounting slot 102 disposed on the upper surface of the base plate 101 and used to engage the slotted sliding plate unit 2, and a mounting hole 103 disposed in the rectangular mounting slot 102 and used to plug the embedded protective frame unit 3.

[0040] In this embodiment, the main material of the slot-hole combination base plate unit 1 is high-strength steel or engineering plastic, the shape of the base plate 101 is rectangular, and the number of the mounting holes 103 is 4 or 6, that is, 2 or 3 mounting holes 103 are arranged at a single long side position of the rectangular mounting slot 102.

[0041] In addition, a support column may be further provided on the lower surface of the bottom plate 101. When the embedded protection frame unit 3 is fully stored, its upper surface height is equal to or lower than the upper surface height of the bottom plate 101, and its lower end insertion position may protrude below the mounting hole 103.

[0042] The grooved sliding plate unit 2 includes a sliding plate 201 arranged on the rectangular mounting groove 102 and used to support the frame roller a, a dual-purpose slot 202 arranged on the upper surface of the sliding plate 201 and used to enter and exit the frame roller a and accommodate the embedded protective frame unit 3, and a rectangular hole 203 arranged in the dual-purpose slot 202 and used to pass through the embedded protective frame unit 3.

[0043] In this embodiment, the long side direction of the sliding plate 201 is parallel to the long side direction of the rectangular mounting groove 102, and is also the reciprocating sliding direction of the sliding plate 201. In this direction, the distance between the wide side of the sliding plate 201 and the wide side of the rectangular mounting groove 102 is relatively large, thereby providing sufficient distance margin for the frame roller a to slide into and out of the dual-purpose slot 202.

[0044] The dual-purpose slot 202 has at least two functions: First, before and after the water pump quality inspection operation, the embedded protective frame unit 3 is received by the dual-purpose slot 202, and at least the upper surface of the former is not higher than the upper surface of the latter, so that the water pump can be slidably installed and removed on the bottom plate 101. For details, please refer to the attached Fig. 9 Otherwise, the water pump needs to be moved as a whole to cross the embedded protective frame unit 3, which is very laborious and dangerous; Second, the portion of the dual-purpose slot 202 located in the sliding direction of the sliding plate 201 is the position where the frame roller a slides in and out, thereby providing a continuous and intermittent vibration effect to the entire forest fire water pump.

[0045] In addition, the height of the embedded protective frame unit 3 on the mounting hole 103 is adjustable, thereby providing a more flexible lateral limiting effect for the forest fire water pump, so that all types of water pumps, whether tall or short, can be fully and appropriately blocked and limited.

[0046] In addition, the long side direction of the rectangular hole 203 is the sliding direction of the sliding plate 201 , and when the latter slides back and forth, the inner wall of the rectangular hole 203 will not hit the embedded protective frame unit 3 .

[0047] Finally, the dual-purpose slot 202 is also provided with a chamfered edge for sliding in and out of the frame roller a. The device is in the ready-to-start state when the forest fire water pump is completely located in the dual-purpose slot 202, and the distance between the frame roller a and the chamfered edge is smaller than the distance between the embedded protective frame unit 3 and the inner wall of the rectangular hole 203, and the one-way sliding distance of the sliding plate 201 is between the above two distance values.

[0048] The embedded protection frame unit 3 includes an insertion rod 301 inserted into the installation hole 103 and passing through the rectangular hole 203, and a protection frame 302 arranged on the insertion rod 301 and used for laterally blocking and limiting the anti-collision frame b.

[0049] In this embodiment, the first structural style of the protective frame 302 is a complete rectangular frame. The advantage of this structural style is that the lateral blocking and limiting strength of the anti-collision frame b is relatively large, while the disadvantage is that its maximum lifting height can only be lower than the inlet and outlet water pipes c, and its practicality may be relatively low.

[0050] On the other hand, the insertion rod 301 and the protective frame 302 are integrally formed, and the protective frame 302 maintains its height after being lifted by: an interference fit between the insertion rod 301 and the mounting hole 103, the two are clamped to each other, or an additional elastic limiting ring 303 is put on the insertion rod 301, thereby preventing the protective frame 302 from falling spontaneously.

[0051] The dual-purpose slots 202 are U-shaped and are two in number; the slotted sliding plate unit 2 also includes a protruding strip 204 disposed on the upper surface of the sliding plate 201 and located between the two dual-purpose slots 202 and used to support the anti-collision frame b after the frame roller a breaks.

[0052] In this embodiment, the frame roller a may break during the water pump inspection process, which is also one of the inspection items. The direct function of the protruding strip 204 is to support the anti-collision frame b before the remaining part of the frame roller a is stuck on the dual-purpose slot 202, thereby avoiding the above-mentioned stuck phenomenon, and its ultimate function is to protect the sliding plate 201 and the cylinder 11.

[0053] Of course, after any frame roller a breaks, the detection operation needs to be stopped immediately, that is, the cylinder 11 needs to be shut down immediately, and then the water pump itself is also shut down. The roller breakage phenomenon occurs during the continuous pumping of the water body, so the water pump can be directly judged as unqualified, even if other functions are completely normal.

[0054] The protection frame 302 is U-shaped and there are two of them. The spacing area between the two protection frames 302 is used for the water inlet and outlet pipes c to pass through relatively.

[0055] In this embodiment, the two U-shaped protection frames 302 are obtained by cutting off the above-mentioned overall rectangular frame-type protection frame 302. The former has the disadvantage that the lateral limiting strength is not as good as the latter, but has the advantages that: First, the lateral limit height of the protection frame 302 on the forest fire water pump is no longer limited by the installation height of the inlet and outlet water pipes c, thereby making the lateral limit effect on the water pump more flexible, and the two U-shaped protection frames 302 can also be set one high and one low; Second, by adapting to the protruding strip 204, even if the protruding strip 204 is set, the protective frame 302 can be completely embedded and retracted to a position below the upper surface of the sliding plate 201, so that the forest fire water pump can be rolled on and off, and there is no need to carry it, which is very labor-saving and convenient.

[0056] The grooved sliding plate unit 2 further includes an emergency ball 205 disposed on the upper surface of the protruding strip 204 and used to support the anti-collision frame b after the frame roller a breaks.

[0057] In this embodiment, the emergency ball 205 can also be replaced by a rolling roller body, which is effective only for a short period of time after the frame roller a breaks and before the cylinder 11 is shut down. Its function is to avoid large relative sliding friction losses between the sliding plate 201 that is still in reciprocating sliding and the anti-collision frame b.

[0058] Generally, during the entire time period required for the normal operation detection of the forest fire fighting water pump on the device, the emergency ball 205 is idle and invalid.

[0059] The grooved sliding plate unit 2 further includes a cylinder shaft connecting groove 206 arranged on the end surface of the protruding strip 204 and the end surface of the sliding plate 201 .

[0060] In this embodiment, the protruding strip 204 is centered upwardly in the width of the sliding plate 201. Another function of the former is that the opening height of the cylinder shaft connecting groove 206 will not be limited by the thickness of the sliding plate 201, thereby adapting to the cylinder type with a relatively high cylinder shaft, thereby greatly improving the practicality of the device.

[0061] The cylinder shaft and the cylinder shaft connection groove 206 can be screwed, snap-fitted, or adhesively fixed. One cylinder shaft connection groove 206 can be provided at each end of the protruding strip 204, so that the grooved sliding plate unit 2 can be adapted to two cylinders 11, so that the reciprocating sliding motion of the grooved sliding plate unit 2 can achieve a faster speed as needed.

[0062] It should be noted that: after the device completes the detection operation, that is, after the cylinder 11 and the water pump are shut down, the dual-purpose slot 202 is not necessarily aligned with the protective frame 302. At this time, it is necessary to manually adjust the position of the sliding plate 201, or further improve the structure of the slotted sliding plate unit 2, for example, a sensor for monitoring the position of the sliding plate 201 is set in the rectangular mounting groove 102 to ensure that when the cylinder 11 is shut down, the sliding plate 201 is stopped at the required position aligned with the protective frame 302 and the dual-purpose slot 202, so that the "embedded" effect of the embedded protective frame unit 3 can take effect.

[0063] The slot-hole combination bottom plate unit 1 further includes a connection pipe limiting ring 104 arranged on the bottom plate 101 .

[0064] In this embodiment, the connecting pipe limiting ring 104 is used to properly lift and fix the connecting pipe 12 to ensure that the two connecting pipes 12 can smoothly enter and exit water. The cylinder mounting plate 105 is in an inverted U shape, and together with the bottom plate 101, it is used to stably install the cylinder 11. A vertical connecting plate can be further provided between the connecting pipe limiting ring 104 and the cylinder mounting plate 105 as required. For details, please refer to the attached Figure 4 .

[0065] The vertical cross-section of the protruding strip 204 is a trapezoid.

[0066] In this embodiment, the sliding wheel 207 or the rolling ball is further provided on the lower surface of the sliding plate 201, so that the action of the cylinder 11 reciprocatingly driving the sliding plate 201 is more labor-saving.

[0067] The inclined surface on the protruding strip 204 corresponds to the "waist" of the right-angled trapezoid, and its function is to make the frame roller a relatively easy to pass over the protruding strip 204, further reducing the difficulty of installing and removing the water pump.

[0068] Correspondingly, if the transition effect of the above-mentioned inclined surface is not used, the water pump can also be installed and removed in a tilted manner on one side, which is also relatively convenient. For details, please refer to the attached Fig. 9 .

[0069] The above detailed description of the implementation methods of the present application is made in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the present application. These are all non-creative modifications and are protected by the patent law as long as they are within the scope of the claims of the present application.
